Writing pandas/matplotlib image directly into XLSX file

Question

I am generating plots in pandas/matplotlib and wish to write them to an XLSX file. I am not looking to create native Excel charts; I am merely writing the plots as non-inter

Answer 1

You can save the image to memory as a file object (not to disk) and then use that when inserting to Excel file:

import matplotlib.pyplot as plt
from cStringIO import StringIO
imgdata = StringIO()

fig, ax = plt.subplots()

# Make your plot here referencing ax created before
results.resid.hist(ax=ax)

fig.savefig(imgdata)

worksheet.insert_image(row, 0, imgdata)
