Re: [matplotlib-devel] Plot or Not: voting to create better matplotlibrc

Regarding whole sets of rcParams, you may want to look at this: https://github.com/tonysyu/mpltools Kevin On 07/20/2013 09:48 PM, Chris Beaumont wrote: 'image.cmap' -- nice! Shows how much I know :) I don't fully agree with Eric that changing the defaults should be treated as an API break -- yes, it may irritate a minority of users, but their code will still run. I'd flip around your argument for the role of rcParams and customization: the majority user is probably someone who doesn't know much about rcParams, or all the ways plots can be customized. *That* is the use case to optimize, not the "legacy" users invested in the current style. However, default tweaking need not be painful. As has been mentioned, a first step would be an easier way to change a whole set of rcParams: something like mpl.set_style('style-name'). As long as one style is 'classic', users can keep the current style for as long as they want. It's a one line fix, and could even be rcParams-settable. With such a framework, it would be possible for people to contribute new styles that ship with MPL, and users could change styles without having to find (and potentially merge) rcParams files from the web. Finally, people could nominate that mature styles be made default (you could even assign version numbers to track the default style as it evolves towards visual awesomeness) chris   On Sat, Jul 20, 2013 at 9:07 PM, Eric Firing <efir...@hawaii.edu> wrote: On 2013/07/20 2:38 PM, David P.

There might even be a better name than "mpl_params"--"settings" comes to mind, or maybe "style". As for parameter tweaking: the defaults shipped with mpl should be changed only rarely, but we should make it as easy as possible for users to customize plots, including coming up with good combinations of style parameters.  In some cases it makes sense to do this via a matplotlibrc file, in other cases it is better to do the parameter setting explicitly at the top of a script. Regarding defaults, note that I said "rarely", not "never". The whole rc system could use a good review--maybe resulting in lots of changes, maybe not--so I welcome the attention you are directing to it.
