ContourPlot example 15
This example demonstrates how to produce a contour plot and an XY
plot and draw them on the same frame. It also shows how to make the
output go to an X11 window, an NCGM, and a PostScript in one program.
The names of the example codes that create this plot are cn15c.c,
cn15f.f, and cn15n.ncl.
There is no resource file for this example, as all the resources are
set in the source code.
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
The HLU FORTRAN program that generates this plot is
The NCL script that generates this plot is
The data for this plot is from a netCDF file called sstdata_netcdf.nc which
contains surface temperature for a series of lat/lon points.
The data file is located in your NCAR Graphics data directory in a
subdirectory called "cdf". You can get the name of the data directory
by typing "ncargpath data" at your shell prompt. If you have netCDF
installed on your system, then you can change directory to where the
netCDF file resides and type "ncdump -h sstdata_netcdf.nc" to view the
header information for this data file.
The examples are installed in the following locations:
The netCDF data file is installed in the following location:
You can copy this example and run it by typing "ng4ex cn15c", "ng4ex
cn15f", or "ng4ex cn15n". 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. You must have the netCDF library
installed on your system in order to compile the C or FORTRAN version
of this example.
