Hi John, I added one line that shows the problem. If you

Hi Charles,
As an aside, you'll be interested in these super secret undocumented
methods of the Subplot class, which I implemented so I wouldn't have
to do the if i % COLS == 1 tricks that I came to know and love in
matlab. I too find myself making lots-o-subplots and blanking out the
labels
Subplot methods:
def is_first_col(self):
def is_first_row(self):
def is_last_row(self):
def is_last_col(self):
which enables you to write your loop
for i in range(1,NUMPLOTS+1):
ax = subplot (ROWS, COLS, i)
ax.set_xticks((0,1,2))
title('Simple ' + str(i))
if ax.is_first_col(): ax.set_ylabel('voltage (mV)')
else: ax.set_yticklabels ()
if ax.is_last_row(): ax.set_xlabel('time (s)')
else: ax.set_xticklabels ()
Now onto your problem. Thanks for the example script. I am not sure
which version of matplotlib you are working with, but it appears there
is a clear bug in Axis.set_ticklabels in the part which reads
for s, label in zip(self._ticklabelStrings, self._ticklabels):
label.set_text(s)
label.update_properties(override)
when len(self._ticklabelStrings) is less than len(self._ticklabels),
the label text doesn't get updated. Duh!
Something like this should work better. At least with
matplotlib-0.32a it handles your example
def set_ticklabels(self, ticklabels, *args, **kwargs):
"""
Set the text values of the tick labels. ticklabels is a
sequence of strings. Return a list of AxisText instances
"""
ticklabels = ['%s'%l for l in ticklabels]
self._ticklabelStrings = ticklabels
override = {}
override = backends._process_text_args(override, *args, **kwargs)
Nnew = len(self._ticklabelStrings)
existingLabels = self.get_ticklabels()
for i, label in enumerate(existingLabels):
if i<Nnew: label.set_text(self._ticklabelStrings[i])
else: label.set_text('')
label.update_properties(override)
return existingLabels

I think users, since my answer includes a *possible* fix which others
may find useful. Let me know how this works for you; I'll take a
closer look on Thurs when I have some breathing room again.
