Re: [Matplotlib-users] Partial coloring of text in matplotlib
What can be done with the current Matplotlib is to use the offset boxes.

Re: [Matplotlib-users] Partial coloring of text in matplotlib
This is the solution which requires the least modification to the original text inserting functions. The only drawback is like you said, it only works with ps backend. Any idea if this could be generalized for other backends?

Re: [Matplotlib-users] Partial coloring of text in matplotlib
In the past, I've thought having some sort of HTML-lite subset would be the most powerful here. So one could do: title(This is bbold/b) Strictly speaking, for colors, one would do: title(This is font color='red'red/font) but that's awfully verbose. I wouldn't have a problem fudging the spec and supporting: title(This is redred/red) since this would never be full-fledged HTML anyway [1]. The advantage of this approach over any of the list-based ones is that different properties can be nested, and I think most people understand the basics of HTML/XML tags. And I agree with Benjamin, that this should be at the Text() constructor level so it works everywhere. I envision it being a sort of peer text parser just as the mathtext parser is now -- in fact a lot of the mathtext machinery would be reused. [1] Of course, I've also considered using something like PythonWebKit to render text for us -- the advantage being we'd also get proper bidi and other internationalization features. But (a) WebKit is another honking dependency and (b) I'm not sure the Python bindings are ready for prime time.

For this reason, I would discourage even implementing such functionality in the core of matplotlib. This functionality doesn't strike me as something that ought to be available everywhere by default - if someone needs it, they can implement it as follows: - import matplotlib.pyplot as plt from matplotlib import transforms def rainbow_text(x,y,ls,lc,**kw): Take a list of strings ``ls`` and colors ``lc`` and place them next to each other, with text ls[i] being shown in color lc[i]. This example shows how to do both vertical and horizontal text, and will pass all keyword arguments to plt.text, so you can set the font size, family, etc. t = plt.gca().transData fig = plt.gcf() plt.show() #horizontal version for s,c in zip(ls,lc): text = plt.text(x,y, +s+ ,color=c, transform=t, **kw) text.draw(fig.canvas.get_renderer()) ex = text.get_window_extent() t = transforms.offset_copy(text._transform, x=ex.width, units='dots') #vertical version for s,c in zip(ls,lc): text = plt.text(x,y, +s+ ,color=c, transform=t, rotation=90,va='bottom',ha='center',**kw) text.draw(fig.canvas.get_renderer()) ex = text.get_window_extent() t = transforms.offset_copy(text._transform, y=ex.height, units='dots') plt.figure() rainbow_text(0.5,0.5,all unicorns poop rainbows ! ! !.split(), ['red', 'orange', 'brown', 'green', 'blue', 'purple', 'black'], size=40) best, -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7 -- Keep Your Developer Skills Current with LearnDevNow!
