Saving plots (AxesSubPlot) generated from python pandas with matplotlib's savefig

Question

I\'m using pandas to generate a plot from a dataframe, which I would like to save to a file:

dtf = pd.DataFrame.from_records(d,columns=h)
fig = plt.figure()
         


        

Answer 1

So I'm not entirely sure why this works, but it saves an image with my plot:

dtf = pd.DataFrame.from_records(d,columns=h)
dtf2.plot()
fig = plt.gcf()
fig.savefig('output.png')

I'm guessing that the last snippet from my original post saved blank because the figure was never getting the axes generated by pandas. With the above code, the figure object is returned from some magic global state by the gcf() call (get current figure), which automagically bakes in axes plotted in the line above.
