TickMark example 2

How to create a TickMark object with bottom and left ticks turned on

This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. It demonstrates how to create a TickMark object with the bottom and left tick marks turned on. The names of the source files for this example are tm02c.c, tm02f.f, and tm02n.ncl.


This module discusses how to create the previous plot using HLU function calls or NCL. A resource file is included with this example, and it is called tm02.res. This file shows how to turn on tickmarks and set their extent.

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 tm02c.c.

Creating the plot using HLU FORTRAN library calls

The HLU FORTRAN program that generates this plot is called tm02f.f.

Creating the plot using NCL

The NCL script that generates this plot is called tm02n.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 (tm02c.c), a FORTRAN program (tm02f.f), or an NCL script (tm02n.ncl). The examples are installed in the following locations:

  • $NCARG_ROOT/lib/ncarg/hluex/tickmark/tm02c.c
  • $NCARG_ROOT/lib/ncarg/hluex/tickmark/tm02f.f
  • $NCARG_ROOT/lib/ncarg/nclex/tickmark/tm02n.ncl
You can copy this example and run it by typing "ng4ex tm02c", "ng4ex tm02f", or "ng4ex tm02n". 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.
