Overlays tab

With the trend object, you can capture and save a snapshot of graphed data and then layer that saved data over current data in a trend. This feature allows you to overlay and compare historical data with current data or any multiple sets of data.
Use the
Overlays
tab to:
  • add snapshots to the trend
  • set up where a snapshot overlays and anchors on the chart
  • specify whether a snapshot is shown or hidden at runtime
  • remove snapshots from the trend
