<Result> = grSourceSeries(<Chart name> , <Series number> , <Source> [, <Details 1> [... [, <Details N>]]])
<Result>: Boolean - True if the source was defined,
- False otherwise. To get more details on the error, use ErrorInfo.
<Chart name>: Control name or character string Name of the chart to be used. This name corresponds to:- the name of the chart defined programmatically with grCreate.
- the name of the Chart control in the window, page or report editor.
<Series number>: Integer Number of the affected series. <Source>: Integer constant Data source of the chart: | | | grCallback | Series filled by a WLanguage function/procedure.
In this case, <Details 1> corresponds to the name of the WLanguage procedure to call.
The procedure is called for each number. This procedure has the following format:
PROCEDURE MyProcedure(<Chart name>, <Series number>,
<Index in series>)
The procedure returns the desired number. To specify the end of the series, the procedure must return False. | | grItem | Series filled from an item.
<Details 1> corresponds to the name of the data file (or query), <Details 2> corresponds to the name of the item. The series will browse through the data file and will take all the values of the item.
If one of the values is not a numeric value, a "hole" is created in the series. | | grListBox | Series filled from a List Box control.
In this case, <Details 1> corresponds to the name of a List Box control. The List Box control is browsed to fill the series. If one of the values is not a numeric value, a "hole" is created in the series. | | grProgramming | Series described programmatically.
<Details 1> can correspond to a series of numbers in the same character string, separated by ";". | | grTable | Series filled from a WLanguage array.
<Details 1> corresponds to the name of the array. <Details 2> can be the index of the column (two-dimensional array) or the name of a member (array of structures). | | grTableColumn | Series filled from a column of a Table control.
In this case, <Details 1> corresponds to the name of a column found in a Table control. This name must correspond to the full name of the column, enclosed in quotes (for example: "<TableName>.<ColumnName>").
The column is browsed to fill the series. If one of the values is not a numeric value, a "hole" is created in the series. |
<Details 1>: Expected type (optional parameter) First expected parameter, according to the type of the data source. <Details N>: Expected type (optional parameter) Last expected parameter, according to the type of the data source.
