Labelbar example 1

How to create a labelbar using default settings

This example demonstrates how to create a labelbar using the default settings. This example was generated using HLU C and HLU FORTRAN library calls and NCL. The names of the example codes that create this plot are lb01c.c, lb01f.f, and lb01n.ncl.

Discussion

This module demonstrates how to create a LabelBar object using mostly default settings. The available resources for this example are listed in a resource file called lb01.res.

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 lb01c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called lb01f.f.

Creating the plot using NCL

The NCL script that generates this plot is called lb01n.ncl.

The data

This plot does not use any external data.

How to run this example

This example can be created using a C program (lb01c.c), a FORTRAN program (lb01f.f), or an NCL script (lb01n.ncl). The examples are installed in the following locations:

  • $NCARG_ROOT/lib/ncarg/hluex/labelbar/lb01c.c
  • $NCARG_ROOT/lib/ncarg/hluex/labelbar/lb01f.f
  • $NCARG_ROOT/lib/ncarg/nclex/labelbar/lb01n.ncl
You can copy this example and run it by typing "ng4ex lb01c", "ng4ex lb01f", or "ng4ex lb01n". A copy of the source file and resource file will be placed in your current working directory. The source code will be compiled and automatically run for you.
