Hey guys, I'm trying to plot quantiles information (percentile 10, 25, 50, 75 and 90). Attached, you'll find a jpged of what I would like to do (this was done using Gnuplot): the vertical line delineates the range from the 10th to the 90th percentile. Small tick bars to either side of the lines mark some additional percentiles: bar to the left for the 25th and bar to the right for the 75th. Finally, dots mark the median. I attempted to use matplotlib.finance modules. In particular, the candlestick stuffs are quite close to what I want. But it didn't work as the XAxis does not correspond to a date information (XAxis values are within the range [1:1780]). Have you got an idea on how I can plot that using matplotlib? Thanks in advance. Keep on rockin' Benoit

Thanks for the advice, Jeff. That's really what I was looking for. I still have another question (I'm sorry for that). Is it possible =20 to increase the linewidth of the box plot (and change the color  =20 i.e., from blue to black)? In the documentation, I don't see any =20 option for boxplot regarding that point (the "widths" option refers =20 to the width of the box, not the line). I agree it is a cosmetic question but I think it would be better in a =20= paper if I can change the linewidth and color. Thanks in advance.

Looking in the matplotlibdevel mailinglist, I found a brand new =20 version of the boxplot method (written by Rob Clewley). This method =20 allows me to have a monochrome plot. This is quite better. I then modified Rob's code for getting linewidth (that's 100% hacking =20=  I'm not proud of it). Sorry for the disturbance.

Benoit, Thanks for pointing this out. I am not a boxplotuser, but a quick look together with your post and Rob's suggests to me that some version of Rob's enhancements should be committed to svn. I think it might be possible to simplify the argument list; a bit of code review would be good. Regarding your modification of linewidth, do you think this really needs to be yet another kwarg, or is it adequate to be able to adjust the linewidth with a line of user code after calling boxplot? The method returns a dictionary with the various lists of line objects that have been drawn, so any properties of those objects can be altered. Perhaps a more thorough updating of boxplot would use collections instead of lists of lines. Any volunteers? I am not going to do it. This would speed it up for cases with many points, but maybe boxplot is normally used with few enough points that this doesn't matter.

Eric, > Regarding your modification of linewidth, do you think this really =20 > needs to be yet another kwarg, That's what I did (I'm not a Python expert).
