Bringing up an old thread, but just curious if this can be done with the plot
command as well, as in:
plt.plot(X,Y[1:3,:].T,c=['blue','red'])
Thanks,

Send an example of how you're handling the plotting. I have had similar

Hello,
I'm trying to plot text objects with the color used in m.scatter. My goal is
to individually label each scatter object. I've tried the following:
circles=m.scatter(cx,cy,zsize,zlevel,cmap=cmap)

Must be something about asking the right question...
This works perfectly.
For those interested, my code is now as:
dmn = 0.1
dmx = 100
logspace = 10.**np.linspace(dmn, dmx, 100)
clevs = logspace
colmap = pyplot.get_cmap('gist_ncar')

In mpl_toolkits.basemap there is a module cm.
I have been using the cm.s3pcpn colormap for some plots which require
logarithmic coloring. The cm.s3pcpn_l colormap is also available (apparently
a linear version).
I wanted to know whether there were any other logarithmic colormaps
available...

I am trying simply to shrink the font size and rotate xaxis labels:

ax1.plot_date(x,y,'r')
ax1.set_xticklabels(plt.gca().get_xmajorticklabels(),

in a script it would be better to use the axis method, but
apparently it is different from the gca() method. This is what I don't
