I have just started experimenting with matplotlib, since I often come across instances where I need to plot some data, for which matplotlib seems an excellent tool. I attempted to adapt the ellipse example in the main site, so as to draw two circles instead, how ever after running the code, I find that none of the patches are displayed, I am not able to figure out what exactly is wrong... here is the code. Thanks in Advance. import numpy as np import matplotlib.pyplot as plt import matplotlib import matplotlib.patches as mpatches plt.axis([-3,3,-3,3]) ax = plt.axes([-3,3,-3,3]) # add a circle art = mpatches.Circle([0,0], radius = 1, color = 'r', axes = ax) ax.add_artist(art) #add another circle art = mpatches.Circle([0,0], radius = 0.1, color = 'b', axes = ax) ax.add_artist(art) print ax.patches plt.show() Continue reading...
