Zooming Graphs and Charts (PDA Module, Touch Panel Module)
Complete the following steps to enable zooming in a graph or chart in a PDA or Touch Panel application.
- Place a Zoom Chart or Graph VI on the block diagram for each graph or chart for which you want to enable zooming.
- Determine the tabbing order of the graph or chart.
- Wire the tabbing order number or the control reference of the graph or chart to the Zoom Chart or Graph VI and provide a way for users to select the type of zoom functionality. For example, you can provide zoom selection from an enumerated list control or a custom run-time menu.
- (PDA Module) Build the PDA VI into a PDA application.
- (Touch Panel Module) Build the Touch Panel VI into a Touch Panel application.

Note If you are zooming a graph or chart with a log scale in a PDA or Touch Panel application, it might appear as if nothing has happened because the scale conforms to the log scale. To resolve this problem, choose a larger zoom rectangle. |
