There are functions that you can include in order to get more information: $MAX, $MIN, $START, $FINAL and $END. By default the value that the variable gets is the one that triggers the event which would be the $START function. In order to use them just add them on the Report Argument when selecting the variable according to the convention: $FUNCTION([VARIABLE]).

$FINAL() is empty on an ongoing event, and the end value when the event finish. $END is the last value of on ongoing event, and the end value when the event finish.

Example: $MIN([SIGNAL_SPEED])
