[matplotlib-devel] Patch: set capsize of errorbar via matplotlibrc

[Hans D. <han...@ki...>]

Hi fellow developers,

I am using matplotlib in particle physics where we generally do not plot 
the little end caps of error bars. They add no information, but they 
make the plot harder to read, especially if it is a busy plot.

In physics, we follow the general aesthetic rule to maximise the "data 
to ink ratio", which means that the information should be presented with 
a minimum of optical gimmicks.

So, I end up calling errorbar everytime with capsize=0. I argue that 
having end caps or not is a global style option, and therefore it makes 
sense to put this into matplotlibrc.

I prepared a patch in order to do that and would like you to include it 
into the distribution.

Please tell me what you think of it.
