We had some working code were were using with 0.87, but when we try to use it
with 0.90, we get the following error:
File "/usr/local/lib/python2.4/site-packages/EEIGraph/BaseGraph.py", line 250,
in plotDate
line = self.main_axes.plot_date( g[:,0], g[:,1] )
File
"/usr/lib/python2.4/site-packages/matplotlib-0.90.0-py2.4-linux-i686.egg/matplotlib/axes.py",
line 2395, in plot_date
self.xaxis_date(tz)
File
"/usr/lib/python2.4/site-packages/matplotlib-0.90.0-py2.4-linux-i686.egg/matplotlib/axes.py",
line 1564, in xaxis_date
formatter = AutoDateFormatter(locator)
UnboundLocalError: local variable 'locator' referenced before assignment
It happens in this function:
def xaxis_date(self, tz=None):
"""Sets up x-axis ticks and labels that treat the x data as dates.
tz is the time zone to use in labeling dates. Defaults to rc value.
"""
thislocator = self.xaxis.get_major_locator()
if not isinstance(thislocator, DateLocator):
locator = AutoDateLocator(tz)
self.xaxis.set_major_locator(locator)
thisformatter = self.xaxis.get_major_formatter()
if not isinstance(thisformatter, DateFormatter):
formatter = AutoDateFormatter(locator)
self.xaxis.set_major_formatter(formatter)
It seems to happen when thislocator is an AutoDateLocator, thus locator is an
AutoDateLocator, thus locator is not set, but thisformatter is a
AutoDateFormatter, which doesn't seem to satisfy isinstance(thisformatter,
DateFormatter)
I don't know enough about matplotlib internals to speculate further.
Any hints?
