XyPlot example 8

Using irregular points to set a plot transformation

This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. This example demonstrates how to create a plot that uses irregular points to change the plot transformation. This example also shows how to read data from an ASCII file using the asciiread function (NCL only). The names of the source files for this example are xy08c.c, xy08f.f, and xy08n.ncl.


This module discusses how to create this plot using HLU function calls and NCL. A resource file is included with this example, and it is called xy08.res. This file is used to change the default resource settings for the plot.

A detailed discussion of how this example works appears in its source code.

Creating the plot using HLUs

The HLU C program that generates this plot is called xy08c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called xy08f.f.

Creating the plot using NCL

The NCL script that generates this plot is called xy08n.ncl.

The data

The data for this plot is read from an ASCII file called xy08.asc.

How to run this example

You can produce this example by using a C program (xy08c.c), a FORTRAN program (xy08f.f), or an NCL script (xy08n.ncl). The examples are installed in the following locations:

The resource file for this example is located in:

You can copy this example and run it by typing "ng4ex xy08c", "ng4ex xy08f", or "ng4ex xy08n". 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.
