VectorPlot example 7
This example can be created using HLU function calls or NCL. It
emulates the LLU example "fcover" and shows how to overlay contours
and vectors on a MapPlot. The names of the source files for this
example are vc07c.c, vc07f.f, and vc07n.ncl.
This module discusses how to create this plot using NCL or HLU C or
FORTRAN calls. A resource file is included with this example, and it
is called vc07.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
The HLU C program that generates this plot is called vc07c.c.
The HLU FORTRAN program that generates this plot is called vc07f.f.
The NCL script that generates this plot is
The data for this plot are from an ASCII file called "fcover.dat".
The data file is located in your NCAR Graphics examples directory.
You can get the name of the examples directory by typing "ncargpath
examples" at your shell prompt.
This example can be created using a C program (vc07c.c), a FORTRAN
program (vc07f.f), or an NCL script (vc07n.ncl). The example is
installed in the following locations:
The resource file for this example is located in:
The ASCII data file is installed in the following location:
You can copy this example and run it by typing "ng4ex vc07c", "ng4ex
vc07f", or "ng4ex vc07n". A copy of the source file and resource file
will be placed in your current working directory. The source code will
be automatically compiled, linked, and run for you.
