Accessing the Matplotlib Objects



In [1]:

    
import autofig
import numpy as np
import matplotlib.pyplot as plt



In [2]:

    
#autofig.inline()



In [3]:

    
x = np.linspace(0,0.1,11)
y = x**2



In [4]:

    
mplfig = autofig.plot(x=x, y=y, show=True)

matplotlib figure

When autofig completes a draw (either with autofig.draw() or passing show=True to a plot or mesh call), a matplotlib figure instance object is returned. You can then act on this with anything supported by your version of matplotlib (see the matplotlib figure API docs)
