ContourPlot example 12
This example demonstrates how to use HLUs and NCL to create a masked,
filled contour plot over a map of Africa. The names of the example
codes that create this plot are cn12c.c, cn12f.f, and cn12n.ncl.
Discussion
Some of the resources are controlled through a resource file called cn12.res.
A detailed discussion about how to create the plot appears in the
comments of the source code for the example.
The HLU C program that generates this plot is
called cn12c.c.
The HLU FORTRAN program that generates this plot is
called cn12f.f.
The NCL script that generates this plot is
called cn12n.ncl.
The data for this example are generated using the GENDAT subroutine.
However, the NCL script reads data from an ASCII data file called
cn12n.asc.
The examples are installed in the following locations:
- $NCARG_LIB/ncarg/hluex/contourplot/cn12c.c
- $NCARG_LIB/ncarg/hluex/contourplot/cn12f.f
- $NCARG_LIB/ncarg/nclex/contourplot/cn12n.ncl
The resource file for this example is located in:
- $NCARG_LIB/ncarg/resfiles/contourplot/cn12.res
The data for the FORTRAN version of this example is located in:
- $NCARG_LIB/ncarg/data/asc/cn12n.asc
You can copy this example and run it by typing
"ng4ex cn12c",
"ng4ex cn12f", or "ng4ex cn12n". 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.
