matplotlib-devel Mailing List for matplotlib

Andrew,
jpPlot looks very promising. I will definitely try to add that into my
code. 
Thanks, 
Brian

Thanks Nadia. Fixed in svn r8128.

Philip: I've added the near-sided perspective projection to basemap svn 
- see the nsper_demo.py example. It only works if the earth is assumed 
to be a perfect sphere (no ellipsoids allowed).

Hi MPL developers,
I use an older matplotlib version but this code is the same in SVN, so I thought
I'll mention it.
Thanks,
Nadia

I think you might be interesting in something like a javascript charting
library. This webpage lists some interesting options:

Also, I'm using the percentile method -- meaning that after I get my "normal" distribution of medians, I simply use mlab's percentile function to get the 2.5th and 97.5th percentile of that distribution. The other method (bias-corrected and accelerated) was too complex for me to code up quickly without using Rpy2, and that just seemed silly.

Hi Paul,
I committed a modified version of your code in r8127. This new code is
backwards compatible in the sense that it doesn't change anything for
existing uses of boxplot, but allows use of the bootstrapped approach by
specifying "notch=1" and "bootstrap=N" where N is the number of
resampling steps.
Thanks,
Andrew
