Patch: more Pythonic rc handling

The standard RC parameters handling in Matplotlib has always troubled me. The
syntax rc('figure.subplot', top=0.9) is not very conveniet if one wants to
change a singe property. Direct rcParams['figure.subplot.top'] seems better
suited in this case.

However, as the dots are already used to indicate grouping in RC, it seems
very natural to use the syntax like:

rc.figure.subplot.top = 0.9

In my opinion this is very elegant, efficient and much Pythonic approach.

In the attachment I include a path to the current git main repo, which enables
this way of handling RC properties. I would appreciate very much if they were
reviewed and included in the next release of Matplotlib (the patch is not
particularly large).

Best regrds,
Maciek

Hi everyone,

We're part of the summer 2012 batch at Hackerschool (www.hackerschool.com) and we chose to spend this week contributing to matplotlib. We already submitted a handful of pull requests for bugs but we are looking for more to do.

Are there any open issues or features you would like us to work on?

- Amy, Vera, Beverly and Alan

Awesome!

Here is a quick list of all github issues tagged with “wishlist”:

Thanks!

I probably should at some point submit this as a wishlist item, but I thought I'd mention it here:

The other day, I was looking to make a ylabel with text of two different colors (I wanted to use the ylabel in a twinx rather than a legend to show that two of three plots on an axis used a particular scale). See also:

http://stackoverflow.com/questions/9169052/partial-coloring-of-text-in-matplotlib

Unfortunately, I don't believe this solution is going to work in a xlabel or ylabel without finding the location of the ylabel and putting these concatenated text objects there.

It would be nice to have the label and title methods take a Text object (and a list of text objects -- each of whom could supply a piece of different colored text) in addition to a string.

A list of text objects would be automagically concatenated together. How to generalize alignment of multiple text objects? Haven't thought that far yet.

Either that or develop some additional color markup (and a parser) inside a string. Admittedly a bigger project -- though probably a better solution.

I have posted the path to the github fork, as described in developer manual of
matplotlib. The most recent changes are here:

For reference, I believe Ben's referring to #697 [1], for which I provided a
possible implementation, which has the automagic concatenation you seek.
