Interactive plotting widgets

============================

Overview

--------

The `pyplot` module provides an interactive plotting interface similar to

`Matplotlib`'s, i.e. with MATLAB-like syntax.

The :py:mod:`.pyplot` module was designed to be as close as possible

to the :py:mod:`matplotlib.pyplot` module, so that one could easily switch

between these two modules by simply changing the import statement. Basically,

if :mod:`plotpy` does support the plotting commands called in your script, replacing

``import matplotlib.pyplot`` by ``import plotpy.pyplot`` should be enough, as

shown in the following example:

* Simple example using `matplotlib`::

import matplotlib.pyplot as plt

import numpy as np

x = np.linspace(-10, 10)

plt.plot(x, x**2, 'r+')

plt.show()

* Switching from `matplotlib` to :mod:`plotpy` is trivial::

import plotpy.pyplot as plt # only this line has changed!

import numpy as np

x = np.linspace(-10, 10)

plt.plot(x, x**2, 'r+')

plt.show()

Examples

--------

>>> import numpy as np

>>> import plotpy.pyplot as plt

>>> plt.ion() # switching to interactive mode

>>> x = np.linspace(-5, 5, 1000)

>>> plt.figure(1)

>>> plt.subplot(2, 1, 1)

>>> plt.plot(x, np.sin(x), "r+")

>>> plt.plot(x, np.cos(x), "g-")

>>> plt.errorbar(x, -1+x**2/20+.2*np.random.rand(len(x)), x/20)

>>> plt.xlabel("Axe x")

>>> plt.ylabel("Axe y")

>>> plt.subplot(2, 1, 2)

>>> img = np.fromfunction(lambda x, y: np.sin((x/200.)*(y/200.)**2), (1000, 1000))

>>> plt.xlabel("pixels")

>>> plt.ylabel("pixels")

>>> plt.zlabel("intensity")

>>> plt.gray()

>>> plt.imshow(img)

>>> plt.figure("plotyy")

>>> plt.plotyy(x, np.sin(x), x, np.cos(x))

>>> plt.ylabel("sine", "cosine")

>>> plt.show()
