ChartScatterMS Sub

 Action
 Draws multi-series scatter charts.


 Syntax
 ChartScatterMS env, valx!(), valy!(), n%, first%, last%, serieslabel$()

 Remarks
 The ChartScatterMS procedure uses the following arguments.

 env
 ---
 A variable dimensioned as type ChartEnvironment.

 valx!()
 -------
 A two-dimensional single-precision array of values for multiple series of
 data for the x axis.

 valy!()
 -------
 A two-dimensional single-precision array of values for multiple series of
 data for the y axis.

 n%
 --
 An integer that contains the number of data items to be charted.

 first%
 ------
 An integer that indicates the first series to be charted.

 last%
 -----
 An integer that indicates the last series to be charted.

 serieslabel$()
 --------------
 A one-dimensional string array that contains labels for the different data
 series.


 Dimensions for the valx!(), valy!() and serieslabel$() arrays are declared
 as follows.

 DIM valx!( 1 to n%, first% to last%)
 DIM valy!( 1 to n%, first% to last%)
 DIM serieslabel$( first% to last%)

 To chart all series, set first% to 1 and last% to the last series number in
 array value!(). To chart several contiguous series, set first% to lowest
 series number and last% to the highest series number desired.

 An analysis routine called AnalyzeScatterMS (included in the Presentation
 Graphics toolbox) uses the same arguments as ChartScatterMS.
 AnalyzeScatterMS analyzes and defines parameters in the chart environment
 based on the input data, but it does not print a chart on the screen.
