Georg, See errorbar_demo.py in the examples directory. The last example sets the y-axis to a log scale; it should also work if you use the same method to set both scales to log, so it would be like this:
ax = subplot(111) ax.set_xscale('log') ax.set_yscale('log') errorbar(t, s+2, e, f, fmt='o') You may need to be careful to keep all values, including errorbar limits, positive.
