python - Matplotlib: get colors and x/y data from a bar plot -

i have bar plot , want colors , x/y values. here sample code:

import matplotlib.pyplot plt def main():     x_values = [1,2,3,4,5]     y_values_1 = [1,2,3,4,5]     y_values_2 = [2,4,6,8,10]     f, ax = plt.subplots(1,1)     ax.bar(x_values,y_values_2,color='r')     ax.bar(x_values,y_values_1,color='b')     #any methods?     plt.show() if __name__ == '__main__':     main() 

are there methods like ax.get_xvalues(), ax.get_yvalues(), ax.get_colors(), can use extract ax lists x_values, y_values_1, y_values_2 , colors 'r' , 'b'?

the ax knows geometric objects it's drawing, nothing keeps track of when geometric objects added, , of course doesn't know "mean": patch comes bar-plot, etc. coder needs keep track of re-extract right parts further use. way common many python programs: call barplot returns barcontainer, can name @ time , use later:

import matplotlib.pyplot plt def main():     x_values = [1,2,3,4,5]     y_values_1 = [1,2,3,4,5]     y_values_2 = [2,4,6,8,10]     f, ax = plt.subplots(1,1)     rbar = ax.bar(x_values,y_values_2,color='r')     bbar = ax.bar(x_values,y_values_1,color='b')     return rbar, bbar  if __name__ == '__main__':     rbar, bbar = main()     # stuff barplot data:     assert(rbar.patches[0].get_facecolor()==(1.0,0.,0.,1.))      assert(rbar.patches[0].get_height()==2)
