Thanks for your answer. I'm actually looking to plot filled curves whose
points are lat/lon points on top of a given background map. The problem
experienced is misrepresentation of background map when I insert it using
warpimage(), the only function to do this I found so far.

Hi,

If you're just looking for points, you can use ax.scatter(). It will plot
the points. Also, make sure you set the zorder keyword argument in the
scatter.
Example:
x=range(10)
y=range(10)
z=range(10,20)
ax.scatter(x,y,c=z,zorder=10)
Hope this helps,

data on a background map: bkgmap.png

So far I only found out about warpimage() to do this but only part of
bkgmap.png comes up in the output image. I think this is becau
