kwargs are ignored in Series.plot · Issue #1636 · pandas-dev/pandas (original) (raw)

It seems that some kwargs (like mew and ms) given to the Series.plot method are being ignored.

I'm running pandas.0.8.0 and matplotlib 1.1.0 on Archlinux, Python 2.7.3 with ipython 0.12.1, and starting ipython via ipython2 --pylab=qt.

The following code produces the erroneous behaviour. The mpl plotting works just fine, whereas the pandas plotting ignores ms and mew arguments.

import matplotlib as mpl
from numpy import random
import pandas
print pandas.__version__

test = pandas.Series(random.randn(120),
                     index=pandas.date_range(start="2000-01-01",
                                             end="2009-12-31",
                                             freq=pandas.datetools.MonthBegin()))

mpl.pyplot.figure()
# this produces the correct markers
mpl.pyplot.plot(test, '.', ms=12.)

mpl.pyplot.figure()
# this ignores the ms kwarg
test.plot(style='.', ms=12.)

It would be okay to use matplotlib's plotting function, but I'm dealing with time series, and I don't think matplotlib's support for dates is too convenient.

Is this a bug, or am I just doing it wrong?
