The setVariable command in Plot is supported with a new feature – it can serve as an activity.
It is now possible to check whether the value set in Plot is correct or not. All you have to do to make it work is to set the correct values in the “Variables” -> “Expected” property. The correct answer is when all the values of the variable correspond to the ones enterd in the “Expected” box.
