How can you scale the Gantt view?
In the documentation there is a mode tag that can be added to a gantt view. This tag allows you to scale the time duration of the gantt view. But it doesn't seem to do anything in reality.
<gantt date_stop="date_finished" date_start="date_start" string="Productions" default_group_by="routing_id" mode ="month"> </gantt>
This code isn't rejected as an XML error, but it doesn't seem to scale the gantt view.
