[Mne_analysis] mne.viz.plot_topo behavior

[Kambiz Tavabi]

Hi all,
A little quirky behavior I can't make sense of; I am trying to show
topography for different conditions using mne.viz.plot_topo however I keep
getting a type error regarding the number of input arguments
i.e., plot_topo() takes at least X arguments (Y given) that I can't make
sense of. By the way, I assume I can plot any number of conditions using
this function, right?

Here is my code snippet:
# Generate list of evoked objects from conditions names
evokeds = [epochs[name].average() for name in 'retroflex_standard',
'dental_deviant']

*print* evokeds
[<Evoked  |  comment : 'retroflex_standard', time : [-0.100000, 0.500000],
n_epochs : 79, n_channels x n_times : 204 x 601>, <Evoked  |  comment :
'dental_deviant', time : [-0.100000, 0.500000], n_epochs : 80, n_channels x
n_times : 204 x 601>]

>From the tutorial<http://martinos.org/mne/auto_examples/plot_topo_compare_conditions.html>

from mne.viz import plot_topo
# Show topography for different conditions
colors = 'yellow', 'green'
title = 'Evoked responses'
plot_topo(evokeds, color=colors, title=title)
conditions = [e.comment for e in evokeds]
for cond, col, pos in zip(conditions, colors, (0.025, 0.07)):
    pl.figtext(0.775, pos, cond, color=col, fontsize=12)
pl.show()

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-120-5809c3f526e8> in <module>()
      5 title = 'Evoked responses'
      6
----> 7 plot_topo(evokeds, color=colors, title=title)
      8
      9 conditions = [e.comment for e in evokeds]

TypeError: plot_topo() takes at least 2 arguments (3 given)

Thanks in advance
