Re: help for overly xy-plot and contour-plot using NCL

Polylines are not the way to go for what you want to do.

There are a number of ways of plotting what you want, all of which are shown in the 'contour-on-contour' example page; if you haven't looked at this then I strongly urge you to.

http://www.ncl.ucar.edu/Applications/conOncon.shtml

The overlay method should work, but without seeing your script it's impossible to see what the problem is. If you haven't already done so, take a look at the example page, if you're still having problems then attach or cut and paste a relatively clean version of your script (commenting is always appreciated).

Subject: help for overly xy-plot and contour-plot using NCL

Hi ncl-talkers,

I was trying to plot a time-height distribution of vertical velocity and overlay the precipitation on it in the same figure. I tried "overlay" and "polylines", but all failed.

Data are omega(time,z) and rain(time). They both have the same time dimension.

In the figure, the x-axis is time dimension, the left y-axis is height, and the right y-axis is precipitation amount.

Any clues to make it happen?

Thank you so much,
Sha
