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 control>,
<Series number>, <Index in series>)
The procedure returns the desired number. To specify the end of the series, the procedure must return False.
| | grItem | Category labels 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 | Category labels 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 | Category labels populated programmatically.

<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 | Category labels 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>").
