Stored procedures
Defines the source of a series.
Example
// Chart control filled from a table column
IF grSourceSeries(CHART_MyChart1, 3, grTableColumn, "Table1.Column1") = True THEN
Info("The source of series 3 is MyColumn from now on")
END
// Chart control based on an item of a SQL query
MyQuery is Data Source

MySQLCode is string = QRY_Query1..SQLCode
HExecuteQuery(MyQuery, hQueryDefault, MySQLCode)
grSourceSeries(CHART_Chart1, 1, grItem, "MyQuery", "TotalBT")
grDraw(CHART_Chart1)

CASE ERROR:
Error(HErrorInfo())
Syntax
<Result> = grSourceSeries(<Chart name> , <Series number> , <Source> [, <Details 1> [... [, <Details N>]]])
<Result>: Boolean
  • True if the source was defined,
  • False otherwise. To find out the error details, use ErrorInfo.
<Chart name>: Character string (with or without quotes)
Name of chart to use. This name corresponds to:
  • the chart name defined by programming with grCreate.
  • the name of Chart control found in the window editor, page editor or report editor.
<Series number>: Integer
Number of the affected series.
<Source>: Integer constant
Data source of the chart:
grTableColumnSeries 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.
grCallbackSeries 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 requested number. To specify the end of the series, the procedure must return False.
grListBoxSeries filled from a list box.

In this case, <Details 1> corresponds to the name of a list box. The list box is browsed to fill the series. If one of the values is not a numeric value, a "hole" is created in the series.
grProgrammingSeries described by programming.

<Details 1> can correspond to a series of numbers in the same character string, separated by ";".
grItemSeries filled from an item.

<Details 1> corresponds to the name of the file (or query), <Details 2> corresponds to the name of the item. The series will browse the 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.
grTableSeries filled from a WLanguage array.

<Details 1> corresponds to the name of the array. <Details 2> can correspond to the subscript of the column (two-dimensional array) or to the name of a member (array of structures).
<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.
Remarks
  • ..Source is used to find out the type of data source of a chart series (column, list, etc.).
  • ..SourceDescription is used to find out the name of the element that corresponds to the data source of a chart series.
