DrillDown (transfer control to new graph object)

Top  Previous  Next

 

Drilldown (| parGraphNpp, graphName, NodeId, NodeName, Xnode, Ynode |)

Drilldown

Unhides, calculates and draws the target graph object

parGraphNpp

A LONG integer that identifies the GraphID FEQ to process

graphName

String text that identifies the graph name.

NodeID

The positional node value of the active graph control that is passed to the drilldown graph control.

NodeName

The positional node name of the active graph control that is passed to the drilldown graph control.

Xnode

The positional X Node coordinate (in Physical Units) of the active graph control that is passed to the drilldown graph control.

Ynode

The positional Y Node coordinate (in Physical Units) of the active graph control that is passed to the drilldown graph control.

The Drilldown method hides the current active graph control, and unhides the target (drilldown) graph control. The target graph object’s data points are calculated and drawn.

Optional parameters can be processed by the target drilldown graph control. This allows the target control to be related to the original graph object.

Implementation:

The Drilldown method is called from the TakeEventOfParent method, when a Drilldown event is posted.
