C Description: This example is similar to the ncargex Autograph
C example "agex13". It shows how to use Irregular
C points to change the transformation of your plot.
C
C The "CoordArrays" object is used to set up the data.
C (The C version uses the "CoordArrTable" object which
C is not available in Fortran or NCL.)
