Legend example 2
How to create a legend and specify marker types
This example demonstrates how to create a legend and specify marker types. 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 lg02c.c, lg02f.f, and lg02n.ncl.
Discussion
This module demonstrates how to create a Legend object using mostly default settings. The available resources for this example are listed in a resource file called lg02.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 lg02c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this plot is called lg02f.f.
Creating the plot using NCL
The NCL script that generates this plot is called lg02n.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 (lg02c.c), a FORTRAN program (lg02f.f), or an NCL script (lg02n.ncl). The examples are installed in the following locations:
