XyPlot example 3

How to set resources and axis coordinates

This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. It demonstrates how to tweak XyPlot resources using a resource file and how to set coordinates for the plot axes. The names of the source files for this example are xy03c.c, xy03f.f, and xy03n.ncl.

Discussion

This module discusses how to create this plot using HLU function calls or NCL. A resource file is included with this example, and it is called xy03.res. This file is used to change the default resource settings for the plot. This example uses the same Y-axis dataset as the xy02 example, but this time values for the X axis are specified, changing the look of 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 xy03c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called xy03f.f.

Creating the plot using NCL

The NCL script that generates this plot is called xy03n.ncl.

The data

The data for this plot is created by calls within the HLU program or NCL script.

How to run this example

This example can be created using a C program (xy03c.c), a FORTRAN program (xy03f.f), or an NCL script (xy03n.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 xy03c", "ng4ex xy03f", or "ng4ex xy03n". 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.
