TickMark example 1

How to create a TickMark object with default settings

This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. It demonstrates how to create a TickMark object using all default settings. The names of the source files for this example are tm01c.c, tm01f.f, and tm01n.ncl.


This module discusses how to create this plot using HLU function calls or NCL. A resource file is included with this example, and it is called tm01.res. This file shows all the default TickMark resources.

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 tm01c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called tm01f.f.

Creating the plot using NCL

The NCL script that generates this plot is called tm01n.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 (tm01c.c), a FORTRAN program (tm01f.f), or an NCL script (tm01n.ncl). The examples are installed in the following locations:

  • $NCARG_ROOT/lib/ncarg/hluex/tickmark/tm01c.c
  • $NCARG_ROOT/lib/ncarg/hluex/tickmark/tm01f.f
  • $NCARG_ROOT/lib/ncarg/nclex/tickmark/tm01n.ncl
You can copy this example and run it by typing "ng4ex tm01c", "ng4ex tm01f", or "ng4ex tm01n". 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.
