Re: overlaying a 1d plot on a 2d contour

[Andrew Wittenberg <Andrew.Wittenberg@xxxxxxxx>]

Hi Wendy,

Billy's solution is a very powerful and general way to do overlays (since
viewports are completely independent).  But in your case you could also
just try:

fill/z=0:150 tid 
plot/ov/vs/line t[gt=h], h
