# Matplot++

Data visualization can help programmers and scientists identify trends in their data and efficiently communicate these results with their peers. Modern C++ is being used for a variety of scientific applications, and this environment can benefit considerably from graphics libraries that attend the typical design goals toward scientific data visualization. Besides the option of exporting results to other environments, the customary alternatives in C++ are either non-dedicated libraries that depend on existing user interfaces or bindings to other languages. **Matplot++** is a graphics library for data visualization that provides interactive plotting, means for exporting plots in high-quality formats for scientific publications, a compact syntax consistent with similar libraries, dozens of plot categories with specialized algorithms, multiple coding styles, and supports generic backends.

## Examples

The examples assume we are in the `matplot` namespace. Use these examples to understand how to quickly use the library for data visualization. If you are interested in understanding how the library works, you can later read the details in the complete [article](documentation/README.md). 

### Line Plots

* [Line Plot](#line-plot)
* [Line Plot 3D](#line-plot-3d)
* [Stairs](#stairs)
* [Error Bars](#error-bars)
* [Area](#area)
* [Loglog Plot](#loglog-plot)
* [Semilogx Plot](#semilogx-plot)
* [Semilogy Plot](#semilogy-plot)
* [Function Plot](#function-plot)
* [Function Plot 3D](#function-plot-3d)
* [Implicit function](#implicit-function)

#### Line Plot

```cpp
plot(x,y); 
```

[![example_plot_1](documentation/examples/line_plot/plot/plot_1.svg)](examples/line_plot/plot/plot_1.cpp)

Where `x` and `y` are are any value ranges.

Setters return a reference to `*this` to allow method chaining:

```cpp
plot(x,y)->line_width(2).color("red");
```

The examples use free-standing functions to create plots. You can also use a object-oriented style for plots. We discuss these coding styles in the Section [*Coding Styles*](#coding-styles).

#### Line Plot 3D

```cpp
plot3(x,y);
```

Instead of storing data points, the objects `function line` and `string function` store a function as a lambda function or as a string with an expression. These objects use lazy evaluation to generate absolute data points. The data is generated only when the `draw` function is called.

The `histogram` object creates the histogram edges and bins when the `draw` function is called for the first time with lazy evaluation. Lazy evaluation avoids calculating edges unnecessarily in case the user changes the object parameters before calling `draw`. This object includes several algorithms for automatically delimiting the edges and bins for the histograms. 

#### Boxplot

boxplot(data);
```

Scatter plots also depend on the `line` object. As the line object can represent lines with markers, the `scatter` function simply creates markers without the lines.

#### Scatter Plot 3D

scatter(x,y,z);
```

Binned scatter plots use variations of the histogram algorithms of the previous section as an extra step to place all the data into two-dimensional bins that can be represented with varying colors or sizes. This is useful when there are so many data points that a scatter plot would be impractical for visualizing the data.

#### Plot Matrix

```cpp
plotmatrix(X);
```

[![example_plotmatrix_1](documentation/examples/data_distribution/plotmatrix/plotmatrix_1.svg)](examples/data_distribution/plotmatrix/plotmatrix_1.cpp)

The Plot Matrix subcategory is a combination of histograms and scatter plots. It creates a matrix of `axes` objects on the `figure` and creates a scatter plot for each pair of data sets.
 
#### Parallel Coordinates

Word clouds are generated from text or pairs of words and their frequency. After attributing a size proportional to each word frequency, the algorithm to position the labels iterates words from the largest to the smallest. For each word, it spins the word in polar coordinates converted to Cartesian coordinates until it does not overlap with any other word.

By default, the colors and the sizes depend on the word frequencies. We can customize the colors by passing a third parameter to the `wordcloud` function.

Pareto Charts are a type of chart that uses both $y$ axes. The $y_1$ axis is used to represent bars with the data values in descending order. The $y_2$ axis is used to represent the cumulative distribution function of the data in the $y_1$ axis. By default, a Pareto Chart includes up to 10 items or as many items as needed to represent 95% of the cumulative distribution.

If you need Pareto *fronts* rather than Pareto *charts*, we refer to [Scatter Plots](#scatter-plot) for two-dimensional fronts, [Plot matrices](#plot-matrix) for three-dimensional fronts, or [Parallel Coordinate Plots](#parallel-coordinates) for many-objective fronts. These plot subcategories are described in Section [Data Distribution](#data-distribution). If you also need a tool to calculate these fronts efficiently, we refer to the [Pareto Front Library](https://github.com/alandefreitas/pareto-front).

For the first geography plot, **Matplot++** calls `geoplot()`, which creates a filled polygon with the world map. This first plot receives the tag `"map"` so that subsequent geography plots recognize there is no need to recreate this world map.

The data for the world map comes from Natural Earth. They provide data at 1:10m, 1:50m, and 1:110m scales. The `geoplot` function will initially use the data at the 1:110m scales. The `geolimits` function can be used to update the axis limits for geography plots. The difference between the usual functions for adjusting axis limits (`xlim` and `ylim`) and `geolimits` is that the latter will also update the map resolution according to the new limits for the $x$ and $y$ axis.

The `geolimits` function will query the `figure` size and, depending on the new limits for the axes, update the map to the 1:10m, or 1:50m scales if needed. Because it would be very inefficient to render the whole world map at a 1:10m or 1:50m scale only to display a region of this map, the `geolimits` function also crops the data pertinent to the new region being displayed.

Note that this does not only involve removing data points outside the new limits but it also needs to create new data points on the correct borders to create new polygons coherent with the map entry points in the region. For this reason, the algorithm needs to track all submaps represented as closed polygons in the original world map. If submaps are completely inside or outside the new ranges, we can respectively include or dismiss the data points. However, if the submap is only partially inside the new limits, to generate the correct borders for the polygons, we need to track all points outside the limits to classify the directions of these points outside the limits. We do that by only including points that change quadrants around the new limits so that the map entry points create polygons that look like they would if the complete world map were still being rendered outside these new limits.

If the you are not interested in geographic plots, the build script includes an option to remove the high-resolution maps at 1:10m and 1:50m scales from the library. In this case, the library will always use the map at a 1:110m scale no matter the axis limits.

The function `world_cities` returns a list of major world cities. Its parameters define the minimum distances between cities in the $x$ and $y$ axes. The `greedy_tsp` function is a naive greedy algorithm to find a route between these cities as a Traveling Salesman Problem (TSP). We use the `geoplot` function to draw this route. Note that we use method chaining to define some further plot properties. Finally, the `text` function includes the city names in the map.

By emplacing a polar plot in the `axes`, the `axes` move to a polar mode, where we use the $r$ and $t$ axis instead of the $x$ and $y$ axis.

From the backend point of view, these axes are an abstraction to the user. The data points in the $r$ and $t$ axis are drawn by converting the positions from the polar coordinates $r$ and $t$ to the Cartesian coordinates $x$ and $y$ with the relationships $x=r \cos{t}$ and $y=r \sin{t}$.

Aside from this conversion, these plot subcategories are analogous to line plots, scatter plots, histograms, quiver plots, and line functions.

All these subcategories depend on the `contours` type. They also depend on lazy evaluation for generating the contour lines. When the function `draw` is called in the `contours` class, it preprocesses all contour lines for a three-dimensional function.

Although it is relatively simple to show a heatmap with the values for the $z$-axis, calculating contour lines relative to the $z$-axis is more complex than it might seem at first. We provide the function `contourc` for calculating contour lines. This function uses an adaptation of the algorithm adopted by Matplotlib.

The algorithm creates a quad grid defined by the $x$ and $y$ values. It uses this grid to infer a contour line passing through positions with the same $z$ value. The algorithm sweeps through the grid twice to generate these lines. The first sweep looks for lines that start on the boundaries. The second sweep looks for interior closed loops.

Filled contours are closed polygons for pairs of contour levels. Some polygons for filled contours might be holes inside other polygons. The algorithm needs to keep track of these relationships so that we can render the polygons in their accurate order. To avoid an extra step that identifies this relationship between the polygons, the sweeping algorithm already identifies which polygons are holes for each level.

Once we find the quads with the contour line, the line is generated by interpolating the $z$ values around that quad.

All these subcategories depend on the `vectors` object type. In a two-dimensional plot, for each value of $x$ and $y$ with the position of a vector, it also requires the value of $u$ and $v$ indicating its direction and magnitude. In a three-dimensional plot, the direction and magnitude are defined by $u$, $v$, and $w$.


A quiver plot (or velocity plot) shows a grid of vectors whose direction and magnitude are scaled to prevent the overlap between vectors in subsequent quads.

All these subcategories depend on the `network` class. Graphs are abstract structures that represent objects and relationships between these objects. The objects are represented as vertices and the relationships are depicted as edges.

In an abstract graph, the vertices have no specific position in space. Mathematically, a graph does not depend on its layout. However, the graph layout has a large impact on its understandability. The `network` class can calculate appropriate positions for graph vertices with several algorithms: Kamada Kawai algorithm, Fruchterman-Reingold algorithm, circle layout, random layout, and automatic layout.

The implementation of the Kamada Kawai and Fruchterman-Reingold algorithms depend on the NodeSoup library. The automatic layout uses the Kamada Kawai algorithm for small graphs and the Fruchterman-Reingold algorithm for larger graphs.

These subcategories depend on the `matrix` class. The `matrix` class can have up to four matrices. If it has only one matrix, it is represented with a colormap. If it has three matrices, they represent the red, green, and blue channels. If it has four matrices, the fourth matrix represents an alpha channel to control the transparency of each pixel.

We use the CImg library to load and save images. CImg can handle many common image formats as long as it has access to the appropriate libraries. The **Matplot++** build script will look at compile-time for the following optional libraries: JPEG, TIFF, ZLIB, PNG, LAPACK, BLAS, OpenCV, X11, fftw3, OpenEXR, and Magick++. The build script will attempt to link all libraries from this list to **Matplot++**.

**Matplot++** includes a few convenience functions to manipulate matrices with images: `imread`, `rgb2gray`, `gray2rgb`, `imresize`, and `imwrite`. All these functions work with lists of matrices.

### Annotations

* [Text](#text)
* [Text with Arrow](#text-with-arrow)
* [Rectangle](#rectangle)
* [Filled Polygon](#filled-polygon)
* [Ellipse](#ellipse)
* [Textbox](#textbox)
* [Arrow](#arrow)
* [Line](#line)

The annotations category is meant to create individual objects on the plot rather than representations of data sets. An important difference between the annotations category and other categories is that, by default, the annotations do not replace the plot that already exists in the `axes` object, even if the user does not call the `hold` function.

##### Tiled Layout

Our tiling functions are convenience shortcuts for the subplot functions. If there is no room for the next tile, we automatically rearrange the axes and increase the number of subplot rows or columns to fit the next tile. Use subplots for more control over the subplots.

### Exporting

* [Saving (Manually)](#saving-manually)
* [Saving (Programatically)](#saving-programatically)

#### Saving (Manually)

The interactive plot window has a widget to save the current figure. Because this widget uses the same backend as the one used to produce the interactive image, the final image matches closely what the user sees in the window.

#### Saving (Programatically)

You can programatically save the figure in a number of formats with the `save` function:

```cpp
save(filename);
```

or

```cpp
save(filename, fileformat);
```

[![example_save_1](documentation/examples/exporting/save/save_1.png)](examples/exporting/save/save_1.cpp)

More examples:

[![example_save_2](documentation/examples/exporting/save/save_2_thumb.png)](examples/exporting/save/save_2.cpp)  [![example_save_3](documentation/examples/exporting/save/save_3_thumb.png)](examples/exporting/save/save_3.cpp)  [![example_save_4](documentation/examples/exporting/save/save_4_thumb.png)](examples/exporting/save/save_4.cpp)  [![example_save_5](documentation/examples/exporting/save/save_5_thumb.png)](examples/exporting/save/save_5.cpp)  [![example_save_6](documentation/examples/exporting/save/save_6_thumb.png)](examples/exporting/save/save_6.cpp)  [![example_save_7](documentation/examples/exporting/save/save_7_thumb.png)](examples/exporting/save/save_7.cpp)  [![example_save_8](documentation/examples/exporting/save/save_8_thumb.png)](examples/exporting/save/save_8.cpp) 

The first option (`save(filename)`) infers the appropriate file format from the filename extension. In both cases (`save(filename)` and `save(filename,fileformat)`), this function temporarily changes the backend to a non-interactive backend appropriate to draw the figure. A different backend is used for each format and, depending on the format, the final image does not necessarily match what is on the interactive plot window. The reason is that some file formats purposefully do not include the same features.

 For instance, consider the bar chart generated by
 
 ```cpp
 vector<double> x = {29, 17, 14, 13, 12, 4, 11};
 bar(x);
 ```
 
 If we export the image with
 
 ```cpp
 save("barchart.svg");
 ```
 
 we get the vector graphics 
 
 ![Barchart as SVG file](documentation/img/barchart.svg)
 
 Exporting the image with
 
 ```cpp
 save("barchart.txt");
 ```
 
 generates a representation of the image appropriate for text or markdown files, such as
 
 ```

 This exports the image in a format in which the labels are replaced by latex text so that the plot fits the rest of the document.

## Coding styles

### Member vs. Free-standing Functions

Like in Matplotlib, we support two coding styles: Free-standing functions and an Object-oriented interface.
 
* Freestanding functions: 
    - We call functions to create plots on the current axes
    - The global current `axes` object is the current `axes` object in the current figure in the global figure registry
    - For instance, one can use `plot(y);` to create a line plot on the current axes (or create a new `axes` object if needed). 
    - Also, one can use `plot(ax,y);` to create a line plot on the `axes` object `ax`. 
    - This is less verbose for small projects and quick tests.
    - The library looks for existing axes to create the plot.

* Object-oriented interface: 
    - We explicitly create figures and call methods on them
    - For instance, one can use `ax->plot(y);` to plot on the `axes` object `ax`
    - We can create the same line plot on the current axes by `auto ax = gca(); ax->plot(y);`
    - This is less verbose and provides better control in large projects where we need to pass these objects around
    - The user manages axes handles containing plots.

Assuming the user is explicitly managing the axes to create plots in another function, a more complete example of these styles could be

```cpp
// Free-standing functions
auto ax = gca();
plot(ax, x, y)->color("red").line_width(2);
my_function(ax);
```

and

```cpp
// Object-oriented interface
auto ax = gca();
ax->plot(x, y)->color("red").line_width(2);
my_function(ax);
```

Both examples would generate the same plot. All free-standing functions are templated functions that use meta-programming to call the main function on the current `axes` object. If the first parameter is not an `axes_handle`, it will get an `axes_handle` from the figure registry with `gca` (Section [Figures and Axes](#figures-and-axes)) and forward all parameters to the function in this `axes` object. If the first parameter is an `axes_handle`, the template function will forward all parameters, but the first one, to this `axes` object. This use of templates for the free-standing functions keeps both coding styles maintainable by the developers.

Note that, because the example needs the `axes` object for the function `my_function`, we also need to get a reference to the `axes` object with the free-standing functions. In that case, the free-standing functions are not less verbose than the object-oriented interface.

To adhere to free-standing functions, we could create two versions of `my_function`: one that receives an `axes_handle`, and a second version that would get an `axes_handle` from the figure registry and call the first version. If `my_function` is going to be exposed to other users as a library, this could be a convenience to these users. However, notice that this is only moving the verbosity from the main function to `my_function`. In fact, this is how the free-standing functions in **Matplot++** work.

### Reactive figures

There are also two modes for figures: reactive (or interactive) mode and quiet mode. Figures in reactive mode are updated whenever any of their child objects change. This happens through the `touch` function, that gets called on any child object when it changes its appearance. This creates an interactive mode in which figures are updated as soon as we adjust their properties. If we combine interactive figures with free-standing functions, we have a "Matlab-like style" for plots. This is a coding pattern where the figure registry works as a stream for plots.
The problem with this coding style is that the user might unnecessarily create useless intermediary plots.

Figures in quiet mode are updated by calling the functions `draw()` or `show()` (Section [Figures and Axes](#figures-and-axes)). Unless these functions are called, nothing changes in the figure. The combination of the object-oriented coding style and quiet mode is the "OO-Matplotlib-like style" for plots. This is a coding style in which the user explicitly decides when the plot is shown or updated. This is beneficial to applications that cannot waste computational resources on intermediary figures that might not be valuable to the application.

We generally use free-standing functions with reactive mode and the object-oriented interface with quiet mode. By default, new figures are in reactive mode, unless it is using an non-interactive backend. One can turn this reactive mode on and off with:


* `ion()` or `ioff()` free-standing functions
* `reactive(bool)` or `quiet(bool)` function on the `figure` object
* `figure(true)` or `figure(false)` when explicitly creating a new figure

A more complete example of the reactive mode would be:

```cpp
// Reactive mode
auto f = gcf(false);
auto ax = f->gca();
auto p = ax->plot(ax, x, y);   // draws once
p->color("red").line_width(2); // draws twice more
wait();                        // pause console
```

For convenience, the examples in Section [Plot Categories](#plot-categories) use the reactive mode. The `wait` function pauses the console until the user interacts with the plot window. If the backend is based on process pipes, because these are unidirectional, closing the window is not enough to resume. The user needs to use the console to unblock execution. A similar example is quiet mode would be

```cpp
// Quiet mode
auto f = gcf(true);
auto ax = f->gca();
auto p = ax->plot(x,y);        // does not draw
p->color("red").line_width(2); // does not draw
f->show();                     // draw only once and pause console
```

In this example, the figure is only updated once. The user could replace the `show` function with the `draw` function, but the window would close as soon as execution completes. It is important to use `wait()` and `show()` with caution. These functions are meant for some particular executables so that an interactive plot does not close before the user can see it. It is probably unreasonable to call these functions inside a library because the user would have to manually interfere with the execution to continue.

### Method Chaining

To support a more compact syntax, the library allows method chaining on plot objects. For instance, we can create a simple line plot and modify its appearance by

```cpp
// Using the line handle
auto p = plot(x,y,"--gs");
p->line_width(2);
p->marker_size(10);
p->marker_color("b");
p->marker_face_color({.5,.5,.5});
```

or

```cpp
// Method chaining
plot(x,y,"--gs")->line_width(2).marker_size(10).marker_color("b").marker_face_color({.5,.5,.5});
```

The first code snippet works because `plot` returns a `line_handle` to the object in the `axes`. We can use this line handle to modify the line plot. Whenever we modify a property, the setter function calls `touch`, which will `draw` the figure again if it is in reactive mode. The second option works because setters return a reference to `*this` rather than void. 

### Ranges


The plotting functions work on any range of elements convertible to `double`. For instance, we can create a line plot from a set of elements by

```cpp
set<int> y = {6,3,8,2,5};
plot(y);
```

Any object that has the functions `begin` and `end` are considered iterable ranges. Most `axes object` subclasses use `vector<double>` or `vector<vector<double>>` to store their data. For convenience, the `common.h` header file includes the aliases `vector_1d` and `vector_2d` to these data types.

These conversions also work on ranges of ranges:

```cpp
vector<set<int>> Y = {{6,3,8,2,5},{6,3,5,8,2}};
plot(Y);
```

Unfortunately, because of how templated functions work, one exception is initializer lists. Initializer lists only work for functions that are explicitly defined for them.

### Common Utilities

The headers `common.h` and `colors.h` include a number of utilities we use in our examples. These include naive functions to generate and manipulate vectors and strings; handle RGBA color arrays; convert points to and from polar coordinates; read files to strings; write strings to files; calculate gradients; read, write, and manipulate images; and generate vectors with random numbers. Although some of these functions might be helpful, most functions only operate on `vector<double>` and they are not intended to be a library of utilities. The sole purpose of these algorithms is to simplify the examples.
 
## Motivation and Details

If you are interested in understanding how the library works, you can read the details in the complete [article](documentation/README.md). It describes the relationship between its main objects, the backend interface, how to create new plot categories, limitations, and compares this library with similar alternatives. 

## Integration

### CMake (manual download)

Check if you have [Cmake](http://cmake.org) 3.14+ installed:

```bash
cmake -version
```

Download the whole project and add the subdirectory to your Cmake project:

```cmake
add_subdirectory(matplotplusplus)
```

When creating your executable, link the library to the targets you want:

```
add_executable(my_target main.cpp)
target_link_libraries(my_target PUBLIC matplot)
```

Add this header to your source files:

```cpp
#include <matplot/matplot.h>
```   

### CMake (automatic download)

Check if you have [Cmake](http://cmake.org) 3.14+ installed:

```bash
cmake -version
```

Install [CPM.cmake](https://github.com/TheLartians/CPM.cmake) and then:

```cmake
CPMAddPackage(
    NAME matplotplusplus
    GITHUB_REPOSITORY alandefreitas/matplotplusplus
)
# ...
target_link_libraries(my_target PUBLIC matplot)
```

Then add this header to your source files:

```cpp
#include <matplot/matplot.h>
```   

### Other build systems 

Right now, it really doesn't have support for anything other than CMake. If you really want to use it in another build system you pretty much have to rewrite the entire build script.

If you're not using Cmake, your project needs to include the headers and compile all source files in the [`source`](source) directory. You also need to link with the dependencies described in [`source/3rd_party/CMakeLists.txt`](source/3rd_party/CMakeLists.txt).

Then add this header to your source files:

```cpp
#include <matplot/matplot.h>
```   

### Dependencies

This project requires C++17. You can see other dependencies in [`source/3rd_party/CMakeLists.txt`](source/3rd_party/CMakeLists.txt). CMake will try to solve everything for you.

* Required 
    * olvb/nodesoup (bundled; but you can define `WITH_SYSTEM_NODESOUP=ON` in the cmake command line to use a system-provided version of nodesoup)
    * dtschump/CImg (bundled; but you can define `WITH_SYSTEM_CIMG=ON` in the cmake command line to use a system-provided version of CImg)
    * Gnuplot (for the Gnuplot backend only)
* Optional (for images)
    * JPEG
    * TIFF
    * ZLIB
    * PNG
    * LAPACK
    * BLAS
    * FFTW
    * OpenCV
    * OPENEXR
    * MAGICK

There's an extra target `matplot_opengl` that exemplifies how an OpenGL backend **could** be implemented. It's not a complete backend. If you want to test it, only then there are some extra dependencies.

* Dependencies for the OpenGL backend
    * OpenGL
    * GLAD
    * GLFW3

### Backends

Coming up with new backends is a continuous process. See the complete [article](documentation/README.md) for a description of the [backend interface](source/matplot/backend/backend_interface.h), a description of the current default backend ([Gnuplot pipe](source/matplot/backend/gnuplot.h)), and what's involved in possible [new backends](documentation/README.md#backends). See the directory [`source/matplot/backend`](source/matplot/backend) for some examples. Also, have a look at this example [`test/backends/main.cpp`](test/backends/ogl_main.cpp). 

If you're in a hurry, here is a summary of the backends we have and the backends we have been considering or working on:

* Gnuplot
    * Pros: It seems to be working for everyone. *In practice, this is current default backend you'll get right now.*
    * Cons: Pipes are comparatively slow and unidirectional
* OpenGL
    * Pros: Efficient for many FPS
