XyPlot example 5

How to create an XyPlot with multiple lines using a CoordArrTable object

This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. It demonstrates how to create a plot that contains multiple lines using a CoordArrTable object (C version only). The names of the source files for this example are xy05c.c, xy05f.f, and xy05n.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 xy05.res. This file is used to change the default resource settings for the plot. This example shows one way to create an XyPlot object with multiple lines and multiple lengths using multiple data objects. The C version uses the CoordArrTable object which is not available in the Fortran or NCL versions.

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 xy05c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called xy05f.f.

Creating the plot using NCL

The NCL script that generates this plot is called xy05n.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 (xy05c.c), a FORTRAN program (xy05f.f), or an NCL script (xy05n.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 xy05c", "ng4ex xy05f", or "ng4ex xy05n". 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.
