output to buffer

[rspadim]

i need to save to io.buffer
something like:

buf = io.BytesIO()
mpf.plot(
candles,
type='candle',
mav=(3, 6, 9),
volume=True,
show_nontrading=True,
figratio=(6, 6),
title="Graph",
style='yahoo',
savefig=buf
)
buf.seek(0)

This may be possible now. Presently I don't have time to look into it; maybe in a few weeks.
In the meantime, you may try passing in the value of the savefig= kwarg as a dict (see documentation here, where cell # 7 shows passing in a dict). I think that might work. If that doesn't work, try modifying the savefig kwarg validator here to allow the correct type for an io buffer through. If that works you can submit a pull request for the change. Otherwise, as I mentioned, I may be able to look into this in a few weeks. All the best. Thanks for your suggestion. I think its a great idea.

This is now released to Pypi. Thank you Caleb Coffin @coffincw for implementing this enhancement, and for including examples in the savefig examples notebook
