I have the same problem when trying to set threshold at render callback time, it has no effect. When I update the XML via setXmlData, there is another useful callback: FC_DataLoaded, but I have the same problem: If I call setThreshold in this callback, it has no effect. I'll try the timeout stuff.
gperrot posted a topic in Bug ReportsThe chart attribute interactiveLegend, when set to 1, allow us to toggle one of the data sets. It works well with the RealTimeLine widget. Though this attribute is also documented in RealTimeStackedArea and RealTimeStackedColumn, it does not work at all.
