Re: How to plot cross sections from data on irregular grids

I assume you mean that the data are on a curvilinear grid.
The function "rcm2points" *may* perform the task
    http://www.ncl.ucar.edu/Document/Functions/Built-in/rcm2points.shtml

   lat = (/ .../)
   lon = (/ .../)
   xDen = *rcm2points* (tlat, tlon, data, lat, lon, 0)
