two colors on an axis label?

Community matplotlib-users

Is there a way to have two colors of text on an axis label? I am trying to plot sales dollars and margin dollars on the same graph in different colors. That works well enough but I'm having a hard time labeling the yaxis

plot_date(dates,units,visible = False)
bar(dates,sales,width=5.0,color = salesColor)
bar(dates,margin,width=5.0,color = marginColor)
ylabel("Sales $\nMargin $",color=salesColor)

gets me "Sales $" in the proper color but I can't figure out if it is possible to have "Margin $" in its color as well.

Thanks!

I don't think it's currently possible in any sort of "automatic" way. There have been thoughts of adding support for multiple y labels in the past, but that's a medium-sized chunk of work.

However, as a roundabout approach, you could add figure text:

t = gcf().text(0.5, 0.05, "Margin $",
                horizontalalignment='center', color=marginColor)

The location of the text is specified relative to the whole figure (in the range 0-1). It may take some tweaking to get the positioning right.

BTW -- I don't know if you're using 0.90 or 0.91. In 0.91, since the string "Sales \\nMargin " has two dollar-signs, the section between them will be treated as math notation. To avoid that, you can escape the dollar signs, i.e. "Sales \\$\nMargin \\$".

Cheers,
Mike
