Basic example 6
How to size and position objects
This is an introductory example that shows how to position objects on an output device and how to change their sizes. A simple color table is also defined and used for changing the color of a curve in an XyPlot.
Discussion
This module demonstrates how to create an XyPlot object and a
TextItem object, and then draw them at different positions and scales
on a plot. The example also defines procedures for drawing, positioning,
and scaling plot objects and text objects.
A detailed discussion about how to create the plot appears in the comments of the source code for the example.
Creating the plot using HLU C library calls
The HLU C program that generates this example is called basic06c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this example is called basic06f.f.
Creating the plot using NCL
The NCL program that generates this plot is called basic06n.ncl.
The data
The data for this plot is generated internally by the example code.
