Scale Range Change Event
Installed With: Full Development System
Class: GraphChart Events
Type: Notify
Generated when the user changes the minimum or maximum value of the scale of a graph or chart. The minimum or maximum value changes when the user enters a new value in a scale marker, pans or zooms the graph or chart, or the graph or chart autoscales.
