Basic example 4
This is an introductory example that shows how to select the output for an
NCAR Graphics program. This example demonstrates how to draw the plot using
NCL, HLU C, and HLU FORTRAN library calls in a X Window and in an NCGM
file. The names of the example codes that create this plot are
basic04n.ncl, basic04c.c, and basic04f.f.
This module demonstrates how to specify the type of output for an NCAR
Graphics program. This example shows how to draw the output to a named
NCGM file and to an X Window. The example creates two "workstations" that
specify the type of output that will be used. The example then draws a
contour plot into each of the devices. The output to the X Window is
dynamically displayed. The output to the NCGM file is stored in a file
called ./basic04.ncgm and can be view by using the ctrans utility.
A detailed discussion about how to create the plots 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 HLU NCL program that generates this plot is
The data for this plot was generated internally in the NCL script and in the
HLU source codes. The data is a 5x5 array of integer values.
This example can be generated using an NCL
script (basic04n.ncl), a C program (basic04c.c), or a FORTRAN
program (basic04f.f). The examples are installed in the following locations:
You can copy this example and run it by typing
"ng4ex basic04c", or "ng4ex basic04f". A copy of the source file will be
placed in your current working directory. The source code will be compiled
(if appropriate) and automatically run for you.
