VectorPlot example 1

How to create a VectorPlot using default settings

This example can be created using HLU C library calls, HLU FORTRAN library calls or NCL. It demonstrates how to create a VectorPlot object using the default resources, and it explains how to create data for the plot. The names of the source files for this example are vc01c.c, vc01f.f, and vc01n.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 vc01.res. There is currently nothing of importance in this file.

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

Creating the plot using HLU C library calls

The HLU C program that generates this plot is called vc01c.c.

Creating the plot using HLU FORTRAN library calls

The HLU C program that generates this plot is called vc01f.f.

Creating the plot using NCL

The NCL script that generates this plot is called vc01n.ncl.

The data

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

How to run this example

This example can be created using a C program (vc01c.c), a FORTRAN program (vc01f.f), or an NCL script (vc01n.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 vc01c", "ng4ex vc01f", or "ng4ex vc01n". 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.
