I didn't get a response to the post below from 20 Dec 2007, and also
didn't get a response to posts I made earlier in 2007, so I thought
I'd check whether posts made via gmane make it to the list.
On a probably unrelated note, I checked the list archives at
matplotlib-users Mailing List for matplotlib
and don't see any messages after 17 Dec.

I regularly make log-log errorbar plots where the errors are larger than
the y values. This means that the error bar goes a finite distance
upwards, but should go infinitely far downwards. In Debian's 0.87.7-0.3
package, just the top portion is drawn, which seems like a reasonable
solution. But in Ubuntu's 0.90.1-2ubuntu1 package, trying to do a
plot like this causes an error. Any ideas?Dan
