Accessing
data properties

Contents

Getting information about the data
Saving graph data
Modifying colors, fill patterns, and other data

To access properties related to a graph’s data during execution, you
use PowerScript graph functions. The graph functions related to data fall
into several categories:

Functions that provide information about a graph’s data
Functions that save data from a graph
Functions that change the color, fill patterns, and other visual
properties of data

How to use the functions

To call functions for a graph in a graph control, use the following
syntax:

graphControlName.FunctionName ( Arguments )

1	graphControlName.FunctionName ( Arguments )

For example, to get a count of the categories in the window graph
gr_printer, code:

Ccount = gr_printer.CategoryCount()

1	Ccount = gr_printer.CategoryCount()

Different syntax for graphs in DataWindows

The syntax for the same functions is more complex when the graph
is in a DataWindow, like this:

DataWindowName.FunctionName ( "graphName", otherArguments... )

1	DataWindowName.FunctionName ( "graphName", otherArguments... )

For more information, see Manipulating Graphs in DataWindow Programmers Guide.
