XyPlot example 14
This example can be created using HLU C library calls, HLU FORTRAN
library calls, or NCL. It demonstrates the data manipulation
capabilities available in NCAR Graphics and how to create data
objects. The names of the source files for this example are xy14c.c,
xy14f.f, and xy14n.ncl.
Discussion
This module discusses how to create this plot using HLU function calls
or NCL, and it demonstrates some of the data manipulation capabilities
that are available with NCAR Graphics. The example creates a series of
plots that use CoordArrays objects for managing data.
The NCL version of this example also demonstrates how to use some of
the data manipulation features and functions of the language to
subsample or thin data and perform conversions and other mathematical
operations on the data.
A resource file is not used with this example.
A detailed discussion of how this example works appears in its source
code.
The HLU C program that generates this plot is
called xy14c.c.
The HLU FORTRAN program that generates this plot is
called xy14f.f.
The NCL script that generates this plot is called
xy14n.ncl.
The data for this plot is generated from within the program.
The examples are installed in the following locations:
- $NCARG_LIB/ncarg/hluex/xyplot/xy14c.c
- $NCARG_LIB/ncarg/hluex/xyplot/xy14f.f
- $NCARG_LIB/ncarg/nclex/xyplot/xy14n.ncl
You can copy this example and run it by typing "ng4ex xy14c", "ng4ex
xy14f", or "ng4ex xy14n". 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.
