ChartMS Sub

 Action
 Draws multi-series bar, column, and line charts.


 Syntax
 ChartMS env, cat$(), value!(), n%, first%, last%, serieslabel$()

 Remarks
 The ChartMS procedure uses the following arguments.

 env
 ---
 A variable dimensioned as type ChartEnvironment.

 cat$()
 ------
 A one-dimensional string array of category labels.

 value!()
 --------
 A two-dimensional single-precision array of values that contains multiple
 series of data.

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

 first%
 ------
 An integer that indicates the first series in array value!() to be charted.

 last%
 -----
 An integer that indicates the last series in array value!() to be charted.

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


 Dimensions for the value!() and serieslabel$() arrays are declared as
 follows.

 DIM Val!( 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 the lowest
 series number and last% to the highest series number desired.
 An analysis routine called AnalyzeChartMS (included in the Presentation
 Graphics toolbox) uses the same arguments as ChartMS. AnalyzeChartMS
 analyzes and defines parameters in the chart environment based on the input
 data, but it does not print a chart on the screen.
