TextItem example 4

How to use function codes to set text characteristics

This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. This is an extensive example that demonstrates most of the TextItem functionality. It demonstrates, among other things, how to set text position, height, angle, font, and quality. The names of the source files for this example are tx04c.c, tx04f.f, and tx04n.ncl.

Discussion

This module discusses how to create this 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 tx04c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called tx04f.f.

Creating the plot using NCL

The NCL script that generates this plot is called tx04n.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 (tx04c.c), a FORTRAN program (tx04f.f), or an NCL script (tx04n.ncl). The examples are installed in the following locations:

You can copy this example and run it by typing "ng4ex tx04c", "ng4ex tx04f", or "ng4ex tx04n". 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.
