Deletes a series and its data values from a graph.
Graph controls in windows and user objects. Does not apply to graphs within DataWindow objects (because their data comes directly from the DataWindow).
controlname.DeleteSeries ( seriesname )
Argument |
Description |
|---|---|
controlname |
The graph in which you want to delete a series |
seriesname |
A string whose value is the name of the series you want to delete from controlname |
Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument’s value is null, DeleteSeries returns null.
The series in a graph are numbered consecutively, in the order they were added to the graph. When a series is deleted, the remaining series are renumbered.
This script for the SelectionChanged event of a DropDownListBox assumes that the list box lists the series in the graph gr_data. When the user chooses an item, DeleteSeries deletes the series from the graph and DeleteItem deletes the name from the list box:
string ls_name
ls_name = This.Text
gr_data.DeleteSeries(ls_name)
This.DeleteItem(This.FindItem(ls_name, 0))
