[Matplotlib-users] barchart errorbars always in both directions

[Meesters, Aesku.K. I. <mee...@ae...>]

Hi,

I'm following the example in the gallery to do a barchart plot (see
http://matplotlib.sourceforge.net/examples/api/barchart_demo.html ).

In contrast to the example I would like to see the error bars only above
the bars, so I tried

rects2 = ax.bar(ind+width, womenMeans, width, color='y',
                yerr=stds, error_kw = {'barsabove': True,
                                       'ecolor'   : 'k'}

While the 'ecolor' argument gets accepted, 'barsabove' apparently has no
effect (error bars still point up and downwards) - yet, no warning /
error is triggered. Where is my mistake? Or is this a bug (still using
version 1.0.1) with a known work-around?

TIA
Chris
