# PMAgg

A matplotlib GUI backend with interactive capabilities.

#### Introduction

PMAgg is a matplotlib backend with richer interactive capabilities, based on PySide2.
It is currently integrated in the open source project [Pyminer](https://gitee.com/py2cn/pyminer), as the default drawing interface, in order to achieve a drawing window similar to matlab.

#### Usage

```python
import matplotlib
import numpy as np
import matplotlib.pyplot as plt
matplotlib.use('module://PMAgg') # switch to PMAgg backend
x=np.linspace(0,2*np.pi,100)
y=x*np.sin(x)
plt.plot(x,y)
plt.show()
```
