bins provided to plot_pdf not working

[Piotr Fronczak]

Hi,

I try to plot pdf with my own bins. Line 1970 in powerlaw.py in function pdf:

    if 'bins' in kwargs.keys():
        bins = kwargs.pop('bins')

suggests that I can provide bins as an argument to plot_pdf. However (despite removing 'bins' from kwargs in the lines above), kwargs in the parent function plot_pdf still contain element 'bins'. It makes error in plt.plot function from matplotlib since 'bins' is not recognized as an argument. Is this the error in the source code?
