Obtains the number of a category in a graph when you know the category’s label.
Graph controls in windows and user objects, and graphs in DataWindow controls
controlname.FindCategory ( { graphcontrol, } categoryvalue )
Argument |
Description |
|---|---|
controlname |
A string whose value is the name of the graph in which you want to find a specific category, or the name of the DataWindow control containing the graph. |
graphcontrol (DataWindow control only) |
(Optional) A string whose value is the name of the graph in the DataWindow control in which you want to find a specific category. |
categoryvalue |
A value that is the category for which you want the number. The value you specify must be the same datatype as the datatype of the category axis. |
Integer. Returns the number of the category named in categoryvalue in the graph controlname, or if controlname is a DataWindow control, in graphcontrol. If an error occurs, FindCategory returns -1. If any argument’s value is null, FindCategory returns null.
Most of the category manipulation functions require a category number, rather than a name. However, when you delete and insert categories, existing categories are renumbered to keep the numbering consecutive. Use FindCategory when you know only a category’s label or when the numbering may have changed.
These statements obtain the number of a category in the graph gr_prod_data. The category name is the text in the SingleLineEdit sle_ctory:
integer CtgryNbr
CtgryNbr =gr_prod_data.FindCategory(sle_ctgry.Text)
These statements obtain the number of the category named Qty in the graph gr_computers in the DataWindow control dw_equip:
integer CtgryNbr
CtgryNbr = dw_equip.FindCategory("gr_computers", "Qty")
