ContourPlot example 3

Overlaying a ContourPlot on a LogLinPlot

This example demonstrates how to create the plot using HLU C library calls, HLU FORTRAN library calls, or NCL. The names of the example codes that create this plot are cn03c.c, cn03f.f, and cn03n.ncl.

Discussion

Some of the resources are controlled through a resource file called cn03.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 cn03c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called cn03f.f.

Creating the plot using NCL

The NCL script that generates this plot is called cn03n.ncl.

The data

The data for this plot is defined in the header file (cn03c.h) for the C example and in an ASCII data file (cn03f.asc) for the FORTRAN example.

How to run this example

This example can be created using a C program (cn03c.c), a FORTRAN program (cn03f.f), or an NCL script (cn03n.ncl). The examples are installed in the following locations:

The resource file for this example is located in:

The data for the FORTRAN version of this example is located in:

You can copy this example and run it by typing "ng4ex cn03c", "ng4ex cn03f", or "ng4ex cn03n". A copy of the source file, and resource file will be placed in your current working directory. The source code will be compiled and automatically run for you.
