Dear all, I'm trying to write a html page content in which a png figure is generated by matplotlib, with Python3.
However, the following piece of code does not work with matplotlib/Python3 (while it should work with Python2). The error is the following on TypeError: string argument expected, got 'bytes' when on fig.savefig(sio, format="png") Could someone explain me how to do it ? Best regards, Julien -------------------------------------------- import matplotlib.pyplot as plt from io import StringIO fig = plt.figure() ax = fig.add_subplot(111) ax.plot([1,2,3]) sio = StringIO() fig.savefig(sio, format="png") html = """<html><body> ...a bunch of text and html here... <img src="data:image/png;base64,%s"/> ...more text and html... </body></html>""" % sio.getvalue().strip()
