The shout “Drill, Baby, Drill” reminded me to put out the Flex drill down chart sample. One benefit of applying RIA technologies is for data visualization. Flex framework comes with fairly rich set of charting tools. A drill down chart is very good way of looking into data from different levels. If you happened to like to shout “Drill, Flex, Drill” then here is the example.
As you can see there are two charts, pie chart and bar chart. The sample embedded inside the code is sort of census data (population) for different counties with different age ranges. The counties are in 4 digits number ID.
At top level the charts show the population numbers of the counties. When you click a chart item (piece of pie or a bar), the chart drills down to a chart that shows the age ranges within the county. Click again, it drills up back to top level.
To switch the chart you just need click one of the chart icons at the top. Then the chart will flip into another type of chart. That makes it a good example of flipping effect too. The flipping effect is achieved by using the wonderful Sandy 3D engine. What I used is just tiny portion of it, of cause.
I don’t want to bore you with lengthy description. Why don’t you just jump to the Flex Drill Down Chart Example and see for yourself. It’s source view enabled so you can right click to get the source. The meat part is inside the chart.mxml component.
Enjoy it and let me how do you like it.

Awesome. Though, I’ld have enjoyed a little more complexity of the data.
I was wondering if it is possible to use two different data sources for the drill down, and if so could you give me some pointers in how to go about it???
appreciate any help
Thanks !!!
I was wondering how you label the charts. What do you use as the dataprovider?
