VectorPlot example 2
How to set VectorPlot resources using a resource file
This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. It demonstrates how to tweak VectorPlot resources using a resource file. The names of the source files for this example are vc02c.c, vc02f.f, and vc02n.ncl.
Discussion
This module discusses how to create this plot using HLU C function calls, HLU FORTRAN function calls, or NCL. A resource file is included with this example, and it is called vc02.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 vc02c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this plot is called vc02f.f.
Creating the plot using NCL
The NCL script that generates this plot is called vc02n.ncl.
The data
The data for this plot are created by calls within the HLU program or NCL script.
