**Lets-Plot** is a multiplatform plotting library built on the principles of the Grammar of Graphics. 

The library design is heavily influenced by Leland Wilkinson's work [The Grammar of Graphics](https://www.goodreads.com/book/show/2549408.The_Grammar_of_Graphics) describing the deep features that underlie all statistical graphics.

> This grammar [...] is made up of a set of independent components that can be composed in many different ways. This makes [it] very powerful because you are not limited to a set of pre-specified graphics, but you can create new graphics that are precisely tailored for your problem.
> - Hadley Wickham, "[ggplot2: Elegant Graphics for Data Analysis](https://ggplot2-book.org/index.html)"


## Grammar of Graphics for Python [![Latest Release](https://badge.fury.io/py/lets-plot.svg)](https://pypi.org/project/lets-plot)

A bridge between R (ggplot2) and Python data visualization. \

## What is new in 4.8.0

- #### `geom_pointdensity()` Geometry

  <img src="https://raw.githubusercontent.com/JetBrains/lets-plot/master/docs/f-25e/images/geom_pointdensity.png" alt="f-25e/images/geom_pointdensity.png" width="400" height="246">

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/geom_pointdensity.html).
                         
- #### Explicit `group` aesthetic now overrides default grouping behavior instead of combining with it

> [!IMPORTANT]
> **BREAKING CHANGE:**
> 
> Previously, setting `group='variable'` would group by both the explicit variable AND any discrete
> aesthetics (color, shape, etc.). \
> Now it groups ONLY by the explicit variable, matching `ggplot2` behavior. \
> Use `group=[var1, var2, ...]` to group by multiple variables explicitly, \
> and `group=[]` to disable any grouping.

  <img src="https://raw.githubusercontent.com/JetBrains/lets-plot/master/docs/f-25e/images/group_override_defaults.png" alt="f-25e/images/group_override_defaults.png" width="400" height="263">

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/group_override_defaults.html).

- #### `gggrid()`: support for shared legends (parameter `guides`)

  <img src="https://raw.githubusercontent.com/JetBrains/lets-plot/master/docs/f-25e/images/gggrid_legend_collect.png" alt="f-25e/images/group_override_defaults.png" width="500" height="172">

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/gggrid_legend_collect.html).

- #### Better handling of missing values in `geom_line(), geom_path(), geom_ribbon()`, and `geom_area()`

  <img src="https://raw.githubusercontent.com/JetBrains/lets-plot/master/docs/f-25e/images/missing_values_ribbon.png" alt="f-25e/images/missing_values_ribbon.png" width="500" height="192">

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/missing_values_line_path_area_ribbon.html).

- #### `geom_histogram()`: custom bin bounds (parameter `breaks`)

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/geom_histogram_param_breaks.html).

- #### Legend automatically wraps to prevent overlap — up to 15 rows for vertical legends and 5 columns for horizontal ones

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/legend_wrap.html).

- #### `flavor_standard()` resets the theme's default color scheme
  Use to override other flavors or make defaults explicit.

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/flavor_standard.html).

- #### `'left'`, `'right'`, `'top'`, and `'bottom'` legend justification

  See [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/legend_justification.html).

- #### `ggtb()`: Added `size_zoomin` and `size_basis` parameters to control point size scaling behavior when zooming (works with `geom_point` and related layers).

  See: [example notebook](https://raw.githack.com/JetBrains/lets-plot/master/docs/f-25e/ggtb_size_zoomin.html).
