I am using matplotlib in Python to plot a line with errorbars as follows:

plt.errorbar(xvalues, up_densities, yerr=ctl_sds, fmt='-^', lw=1.2, markersize=markersize,
         markeredgecolor=up_color, color=up_color, label="My label", clip_on=False)
plt.xticks(xvalues)

I set the ticks on the x-axis using "xticks". However, the error bars of the last point in xvalues (i.e. xvalues[-1]) are clipped on the right -- meaning only half an error bar appears. This is true even with the clip_on=False option. How can I fix this, so that the error bars appear in full, even though their right side is technically outside xvalues[-1]?

thanks.
