Derived Houses (Turned Charts)

If you want to turn the Chart, select the Traditions/Horary/Derived Houses... menu option. The Derived Houses dialog will open.
Select the House you wish the chart's houses to start from and click the OK button. The chart will be turned and the houses will be counted from the House selected.

Derived Houses is a derived chart, so in order to calculate it you will need to cast the base chart first.
