"pyplot.plot_date()" is not changing the line colors using "color_cycle" #2148
Description
Please, check this question in Stackoverflow:
http://stackoverflow.com/q/17250392/832621
which motivated this bug report.
The OP identified that when trying to plot using plot_date() the colors are not changed accordingly to the color_cycle specified. Actually they are not changing at all.
With plot() it works perfectly.
I tried to change the colors from plot_date() using:
plt.rc('axes', **{'color_cycle':['r', 'g']})
plt.rcParams['axes.color_cycle']=['r','g']
and
setting the matplotlibrc file to the local folder with axes.color_cycle : r, g.
they all did not work.
thank you very much and congratulations for the great package which Matploblib already is!

This isn't a bug, but a design choice. There is a default argument in both
plt.date_plotandaxes.date_plotthat sets the format tobo.See https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/axes.py#L4145 and https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/pyplot.py#L2997

Thank you all for the responses... It is ok that
data_plot()sets the format tobobut why the user cannot change it?WeatherGod commentedon Jun 24, 2013
Probably wasn't a conscious design choice. I move to switch it over to
None, so that the color-cycling mechanism can happen.

Are you going to switch it to
Nonefor the next version? That would be great! Inmatplotlib 1.2.1is there a way to switch it toNone?tacaswell commentedon Jun 24, 2013
@saullocastro Call it as

@tacaswell Thank you! For me it worked doing
plot_date(..., fmt='')plot_date: Set the default fmt to 'o'
plot_date: Set the default fmt to 'o'

fmt is for the shape, what can we use for size.
I tried with m or ms or s but all throw error.
