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)
and then:
CC = circles.get_facecolor()
i=0
for x,y in map(cx,cy):
ax.text(x,y,'some text', color=CC[i])
But if fails because:
m.scatter returns:
matplotlib.collections.CircleCollection object at 0x127898d0
Rather than a list of objects??? Or something. The point is, I would expect
'circles' above to have len==cx, but it does not. What am I doing wrong?
The first thing you are doing wrong is failing to provide a complete,
minimal, self-contained example illustrating the problem. I don't think
the snippet you gave is representative of what you are running. Instead
of map I think you mean zip. Where are you incrementing i?
The general approach of using the get_facecolor() method to get the
array, and indexing into it, is fine. That is not where the problem is.
Once you put together a minimal example, I think you will find the
problem--or that there really is no problem.
A collection is used by scatter because it is much more efficient than a
sequence of objects.
