This seems to be specific to Pandas as opposed to matplotlib. Worked as desired as of a few months ago when I last updated from master. This is the desired behavior in matplotlib: ``` python plt.barh([0,1], [.3, .5], xerr=[[.1,.2], [.3,.4]], color = ['red','green'], ecolor='black') ```  In the Pandas call, it seems to ignore the second error bar argument, both the upper and lower bounds of the error bar are the same: ``` python s = pd.Series([.3,.5]) s.plot(kind='barh', xerr=[[.1,.2], [.3,.4]], color = ['red','green'], ecolor='black') ```
