setp/xticklabel problem
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 stack trace:

TypeError: list indices must be integers Traceback (most recent call last):

File “/usr/lib/python2.4/site-packages/matplotlib/backends/backend_gtk.py”, line 188, in motion_notify_event

FigureCanvasBase.motion_notify_event(self, x, y)

File “/usr/lib/python2.4/site-packages/matplotlib/backend_bases.py”, line 797, in motion_notify_event

func(event)

File “/usr/lib/python2.4/site-packages/matplotlib/backend_bases.py”, line 1085, in mouse_move

try: s = event.inaxes.format_coord(event.xdata, event.ydata)

File “/usr/lib/python2.4/site-packages/matplotlib/axes.py”, line 611, in format_coord

xs = self.format_xdata(x)

File “/usr/lib/python2.4/site-packages/matplotlib/axes.py”, line 593, in format_xdata

val = func(x)

File “/usr/lib/python2.4/site-packages/matplotlib/ticker.py”, line 152, in format_data

return self.__call__(value)

File “/usr/lib/python2.4/site-packages/matplotlib/ticker.py”, line 178, in call

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.

Thanks,

Brian Bowen

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.
