How to download and try this example

Usage: pl -gif stackedarea.htm

//
// demonstrates a script approach to stacked area plots.. note that the
// filter is set up for 4 levels.. and a change in the number of levels 
// requires adjusting the code..
//
// the stack prefab is generally an easier way to go for up to 4 levels
// (this code was actually derived from that)
