How can I set background color of plot?

[ppseverin]

Well, pretty much thats it. I was trying to find a key word for background color but did not found one. Anyone knows how this can be done? Also, how can I add a label/legend to different type of indicators (eg: sma(10) and sma(200))

There are two kwargs that can be used when calling mpf.make_mpf_style(). They are facecolor and figcolor.
Make sure you have read through the entire "styles" tutorial.

Regarding legends, see here and here.

I hope that helps. All the best. --Daniel
