Matplotlib-users,
I am stuck on a problem in trying to label the xaxis for some plots. I
am trying to do something similar to the following:
plot([1,2,3,4], [1,4,9,16])
labels = setp(gca(), 'xticklabels', ['one', 'two', 'three', 'four'])
set(labels, 'rotation', 'vertical')
show()Once the plot is displayed, moving the mouse causes the following

else: return self.seq[pos]Line 3 of the code seems to be the culprit. Does anyone have any idea
on how I might be able to workaround this? I have seen posts
describing issues that seem to be related to the same problem, but I
have not seen a solution.
That doesnt make any sense to me. Line 152 calls self.__call__ with only
one argument, which means the pos argument is initialized to none, and
an empty string should be returned. We need to know what the value of
pos is, please replace line 178 with this:
else:
print pos
return self.seq[pos]
and post the result.
