TextItem example 2
Creating text in a filled colored font with a bounding box
This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. It demonstrates how to draw a text string, set its font, and turn on a bounding box. The names of the source files for this example are tx02c.c, tx02f.f, and tx02n.ncl.
Discussion
This module discusses how to create this plot using HLU function
calls or NCL. A resource file is included with this example; it is
called tx02.res. This file shows
how to set the value of the text string, the text color, font, position, etc.
A 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 tx02c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this plot is called tx02f.f.
Creating the plot using NCL
The NCL script that generates this plot is called tx02n.ncl.
The data
This plot does not use any external data.
