Retrieving Values for 3D Bar Chart Component
A question was posted to my weblog asking how to retrieve the data for the individual bar chart section selected in the 3D Bar chart included as part of the Flash Charting Components Set 2 on DRK 4.
If you are using a listener to capture the select / press event, it is very simple as all of the data is passed to the listener method.
Here is an example:
[code]var dp = new DataProviderClass(); dp.addItem( { data: [1,2,3,4,5,6,7], color: 0xFF0000, label: "red co." } ); dp.addItem( { data: [3,4,5,6,7,8,9], color: 0x00FF00, label: "green co." } ); dp.addItem( { data: [4,9,8,7,6,5,4], color: 0x0000FF, label: "blue co." } ); myBarChart_abc.setDataProvider ( dp ); // define listener object and events var listener = {}; listener.onSelect = function ( chart_component, groupIndex, itemIndex ) { trace("data : " + chart_component.getItemAt(groupIndex).data[itemIndex]) } // add the listener to the chart myBarChart_abc.addListener ( listener );[code]
You can find more information on the Charting Component Set 2 and DRK 4 here.

MattyThanks Mike.

I have real basic question I think. How can I have one group of lets say 3 bar charts (not multiple groups shown in perspective) and have all three bars have different colors? I can't seem to find out how to do this anywhere - is it possible? I was wondering how you would return the bar's instance name and then actually change the color. Thanks!

Sapnahi, Sorry to ask such a basic question, but I'm stuck! I'm using the f3dpiechart component from DRK5. I've placed the empty comp. on the stage and named it. IN the first frame of the main time line i have this code. button_btn.onPress = function(){ var dp = new DataProviderClass(); dp.addItem( { data: [1,2,3,4,5,6,7], color: 0xFF0000, label: "red co." } ); dp.addItem( { data: [3,4,5,6,7,8,9], color: 0x00FF00, label: "green co." } ); dp.addItem( { data: [4,9,8,7,6,5,4], color: 0x0000FF, label: "blue co." } ); myPieChart_apc.setDataProvider ( dp ); } The alert works when i hit the button. But then nothing. The pir chart never gets updated! What am i doing wrong? please help! I've been fiddling for a whole day. Sapna.
