Legend example 3
How to create a legend and specify line types
This example demonstrates how to create a legend and specify line 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 lg03c.c, lg03f.f, and lg03n.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 lg03.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 lg03c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this plot is called lg03f.f.
Creating the plot using NCL
The NCL script that generates this plot is called lg03n.ncl.
The data
This plot does not use any external data.
How to run this example
