VectorPlot example 5

How to overlay a VectorPlot on a MapPlot

This example can be created using HLU function or NCL. It demonstrates how to overlay a VectorPlot on a MapPlot. The names of the source files for this example are vc05c.c, vc05f.f, and vc05n.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 vc05.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 vc05c.c.

Creating the plot using HLU FORTRAN library calls

The HLU Fortran program that generates this plot is called vc05f.f.

Creating the plot using NCL

The NCL script that generates this plot is called vc05n.ncl.

The data

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

How to run this example

This example can be created using a C program (vc05c.c), a Fortran program (vc05f.f), or an NCL script (vc05n.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 vc05c", "ng4ex vc05f", or "ng4ex vc05n". 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.
