Thank you Eric and CM,
I have the below piece of code and added the new definition for minorLocs, but
gets the below error. I believe I did not fully understand the concept you
mentioned.
minorLocs = mdates.MonthLocator(bymonth=[1,3,5,7,9,11],bymonthday=15)
minorFmt = mdates.DateFormatter('%b')
class MonthLetter(minorFmt):
def __init__(self):
DateFormatter.__init__(self, "%b")
def __call__(*args):
s = DateFormatter.__call__(*args)
return s[:1]
minorFmt = MonthLetter()
531 def viewlim_to_dt(self):
--> 532 vmin, vmax = self.axis.get_view_interval()
533 return num2date(vmin, self.tz), num2date(vmax, self.tz)
534
AttributeError: 'NoneType' object has no attribute 'get_view_interva
