Seeing is Believing - QlikView 11 for Developers - page 45

To create a cyclic expression, right-click on the Traffic per year chart and select
Properties… from the context menu.
Since we already have the first expression created, we will continue by beginning to
create the second one. Activate the Expressions tab and click on the Add button. In
the Edit Expression dialog window, type the following expression:
Sum ([# Transported Passengers])
Click on OK and set the label for this expression as # of Enplaned Passengers .
Make sure this second expression is highlighted and click on the Group button. This
will automatically create the cyclic group for our expressions.
Click on the Add button once more and add the following expression:
Sum ([# Transported Freight])
The label for this expression will be Transported Freight . Make sure the new
expression is highlighted and click on the Group button again.
Click on the Add button again to add our last expression:
Sum ([# Transported Mail])
The label for this expression will be Transported Mail . Make sure the new
expression is highlighted and click on the Group button again.
Finally, go to the Number tab and make sure that all of our expressions are
formatted as Integer . Click on OK to apply the changes.
After following this procedure, our chart will have the ability to change its active
expression (metric) through a cycle button (in the form of a circular arrow) that will
be placed at the lower-left corner of the object.
The user can select the measure that he/she wishes to activate by either clicking on it
directly to sequentially change the chart's expression, or by clicking on the little black
down-arrow to display the drop-down menu from which the desired expression can
be selected.
We can also activate the drop-down menu by right-clicking
anywhere inside the cycle button.
