Figure 5-28 Sample collecting snapshot dialog box
The amount of data collected is specified by the % After Trigger setting, found in Utilities > Tool
Setup > Save Data. You can manually stop the snapshot by pressing Y/a at any time during the
data collection.
Once data collection is finished, graphing on-screen stops and the Pause button automatically
changes to the Play button (Figure 5-29).

Sample paused upper toolbar—Play button
Once data collection is finished, graphing on-screen stops and the Pause button automatically
changes to the Play button. A vertical line now appears on each of the data graphs to indicate the
triggering point. The trigger line on the parameter that triggered the snapshot is a different color
than those on the other graphs (Figure 5-30). This makes it easy to determine which parameter
caused the trigger.
