You may want to analyze or visualize the values of a Trial Control variable. For example, you defined a variable named Counter, and:

▪You want to calculate the maximum value that the variable reached during different trials.

▪You want to visualize its values plotted against time.

How to specify a Trial Control variable

1.In the Analysis profile, click the Add button next to Trial Control variable.

2.From the Element list, select the variable you want to analyze.

3.Complete the procedure to add the variable. See Calculate statistics: procedure.

4.To visualize the variable on the timeline, choose the Integrated Visualization.

Notes

▪If you want to calculate the time that the Trial Control variable had a specific value, in the Analysis profile choose Multi-condition instead. There you can select the Trial Control variable and define the selection criteria. See Multi condition

▪If you want to calculate the time based on a From - To criterion, choose Free Interval instead. There you can define, for example an interval From Trial Control variable = 10 to Trial Control Variable = 15. See Free interval
