Hi, I've been reading about box plots and examining the source code for boxplot() lately. While there doesn't seem to be a convention about what the notch specifies, I can't find any justification (or text describing) what exactly the MPL notch is. The source code is:
# get median and quartiles q1, med, q3 = mlab.prctile(d,[25,50,75]) iq = q3 - q1 notch_max = med + 1.57*iq/np.sqrt(row) notch_min = med - 1.57*iq/np.sqrt(row) Is this code actually calculating a meaningful value? If so, what? The original commit was r1098, which doesn't offer a useful comment either (only "aaplied several sf patches" ... looking through the SF bug tracker, I couldn't find anything relevant from before the commit date of 2005-03-28). ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Matplotlib-devel mailing list Matplotlib-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-devel
