Description
Default Value: 0
The FirstValue property defines the index number of the first value to be displayed in the Legend. A Legend can display all active Series names or all points of a single Series.
FirstValue should be set accordingly, taking care not to go above the number of active Series or the number of Series points.
You can use FirstValue to display in the Legend a specific subset of Series or points.
It should be greater or equal than zero, and lower than number of active Series or Series points.
