Can anyone throw some light onto using the drill down option, from what I can find via a google search I can have a main graph and a sub graph and the data in the sub graph changes depending of what I click in the main graph, similar to the filters.
Is this correct, the manual is a bit sparse on what it actually does.
The drilldown functionality in SPJS Charts is not the one described in the Google Chart API pages. You can only drill deeper into the data of the same chart, and basically all you need to do is to go to the “Drilldown and Transpose” tab, enable drilldown and select the drilldown fields. Reload the chart and click one of the columns to see.
