TextItem example 8
Creating a TextItem annotation
This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. This example demonstrates how to set the text spacing and aspect ratio of a string. The names of the source files for this example are tx08c.c, tx08f.f, and tx08n.ncl.

Discussion
This module discusses how to create the previous plot using HLU function
calls or NCL. A resource file is not used with this example.
A detailed discussion of how this example works appears in its source code.
Creating the plot using HLU C library calls
The HLU C program that generates this plot is called tx08c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this plot is called tx08f.f.
Creating the plot using NCL
The NCL script that generates this plot is called tx08n.ncl.
The data
This plot does not use any external data.
How to run this example
You can produce this example by using a C program (tx08c.c), a FORTRAN program (tx08f.f), or an NCL script (tx08n.ncl). The examples are installed in the following locations:
