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.
