I'm looking for a bit more of a comprehensive help than the PDF provided with the MAChartView. I'm having a bit of difficulty putting together a drill down chart. Basically the drill down chart is pretty simple that consist only two MBOs.
First MBO is to query a table and the bar chart will show "System Load" values. So imagine 4 bars on the first chart each titled "System Load 1", "System Load 2", "System Load 3", "System Load 4".
Then the drill down effect would be when the user taps on "System Load 1", the second MBO is invoked and returns another bar chart that breaks down into each location's load value. The query for the second MBO is simple does not even require any input parameter.
The missing piece that I don't seem to see from all the documents on Charts is how the first chart is able to trigger the second chart.
Any help is greatly appreciated. Thanks in advance.
