XyPlot example 15

Creating stacked plots

This example is created using HLU C library calls. It demonstrates how to create a set of 4 'stacked' XyPlots and how to use annotations to simplify the control and sizing of all the plots. The name of the source file for this example is xy15c.c.

Discussion

This module discusses how to create this plot using HLU C function calls. The resource file used with this example is called xy15.res.

This example illustrates the creation of a set of 4 of 'stacked' XyPlots. Each plot has the same X axis. By making the top 3 plots into annotations of the bottom plot, all four plots can be manipulated as a unit. To demonstrate this concept the second frame sets the viewport of the base plot. Because all the annotations have their "amResizeNotify" resource set to true (in the resource file), all the annotation plots resize themselves proportionally to the change in the size of the base plot. Each plot draws a variation of sinusoidal curve.

A more detailed discussion of how this example works appears in its source code.

Creating the plot using HLUs

The HLU C program that generates this plot is called xy15c.c.

Creating the plot using HLU FORTRAN library calls

Currently, the HLU FORTRAN program to generate this plot is not available.

Creating the plot using NCL

Currently, the NCL script to generate this plot is not available.

The data

The data for this plot is generated from within the HLU program.

How to run this example

This example can be produced using a C program (xy15c.c). The example is installed in the following location:

You can copy this example and run it by typing "ng4ex xy15c". 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.
