XyPlot example 14

How to manipulate XyPlot data using NCL

This example is created using NCL. It demonstrates the data manipulation capabilities available in NCAR Graphics and how to create data objects. The name of the source file for this example is xy14n.ncl.

Discussion

This module discusses how to create this plot using NCL, and it demonstrates some of the data manipulation capabilities that are available with NCAR Graphics. The example creates a series of plots that use CoordArrays objects for managing data. The NCL example also demonstrates how to use some of the data manipulation features and functions of the language to subsample or thin data and perform conversions and other mathematical operations on the data. A resource file is not used with this example.

A detailed discussion of how this example works appears in its source code.
