Re: Draw order in PyNGL

Thanks for the info. Ii thin kthat what I was really doing wrong (in
addition to the point you raised) was calling Ngl.draw(plot) after the
polyline were drawn, which I am guessing drew a second contour over the
polyline.

One other question: when overlaying contours on top of a contour map, is
there a way to suppress the box that says "contour from x to y by z" box?
It tried setting the lbLabelBarOn resource to False but that didn't do it.

Thanks,
Charlie Koven
