ContourPlot example 13

Drawing raster contours using inverse map transformations

This example demonstrates how to use inverse map transformations and how to create a raster contour plot. The names of the example codes that create this plot are cn13c.c, cn13f.f, and cn13n.ncl.

Discussion

Resources are controlled through a resource file called cn13.res.

A detailed discussion about how to create the plot appears in the comments of the source code for the example.

Creating the plot using HLU C library calls

The HLU C program that generates this plot is called cn13c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called cn13f.f.

Creating the plot using NCL

The NCL script that generates this plot is called cn13n.ncl.

The data

The data for this plot are created in the example's source code.
