XyPlot example 17

Creating stacked plots

This example is created using HLU C library calls, HLU FORTRAN library calls, or NCL. It demonstrates how to create an XyPlot that has three stacked y axes. The names of the source files for this example are xy17c.c, xy17f.f, and xy17n.ncl.

Discussion

This example reads an ASCII file with 4 variables: lon, u, v, and t. The variables u, v, and t are stacked, each sharing the same X axis, and having their own Y axis.

There is no resource file with this example.

Creating the plot using HLUs

The HLU C program that generates this plot is called xy17c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called xy17f.f.

Creating the plot using NCL

The NCL script that generates this plot is called xy17n.ncl.

The data

The data for this plot is from a file called "xy.asc".

How to run this example

The examples are installed in the following locations:

The ASCII data file is installed in the following location:

You can copy this example and run it by typing "ng4ex xy17c", "ng4ex xy17f", or "ng4ex xy17n". A copy of the source file will be placed in your current working directory. The source code will be compiled and automatically run for you.
