Enables and defines zooming in graphs and charts in PDA or Touch Panel applications. The data type you wire to Control Reference determines the polymorphic instance to use.

Example

Use the pull-down menu to select an instance of this VI.

Select an instance Zoom Chart or Graph_ctlrefZoom Chart or Graph_int32

Zoom Chart or Graph_ctlref

	Control Reference is a reference to the control, which determines the control to read or modify.
	ZoomStyle defines the type of zooming to perform. 0 NoZoom—Performs no zooming 1 Zoom to Rectangle—Zooms in on the x-axis and y-axis 2 X-zoom—Zooms in on the x-axis only 3 Y-zoom—Zooms in on the y-axis only 4 ZoomInPoint—Unsupported value 5 ZoomOutPoint—Unsupported value 6 Zoom to Fit—Restores the chart or graph to its original state

Zoom Chart or Graph_int32

	Tab Order of Control is an array of the tabbing order numbers of the controls. The tabbing order number determines which control to read or modify.
	ZoomStyle defines the type of zooming to perform. 0 NoZoom—Performs no zooming 1 Zoom to Rectangle—Zooms in on the x-axis and y-axis 2 X-zoom—Zooms in on the x-axis only 3 Y-zoom—Zooms in on the y-axis only 4 ZoomInPoint—Unsupported value 5 ZoomOutPoint—Unsupported value 6 Zoom to Fit—Restores the chart or graph to its original state

Example

Refer to the Graph Chart Zoom - Pocket PC.lvproj in the labview\examples\PDA\graph chart zoom directory for an example of using the Zoom Chart or Graph VI.
