          When the user rolls over the first chart, and that rollover event is fired, you could dispatch your own event and have the second chart listen to it. Or perhaps the second chart could simply listen for rollover events where the first chart is the target. Examine these FB2 help topics:

            Firstly thank you for the reply and suggestion.

            Though I feel you have the right idea it brings me no closer to understanding how to call the method to show a data tip label.

            If you have any ideas I'm all ears or eyes as the case may be.

              Mush,
              So, you'll want to do two things:
              1) Set datatips to show on your chart
              2) Create a custom data tip function

              1) <mx:ColumnChart id="myChart" dataProvider="{myprovider}"
              showDataTips="true" dataTipFunction="formatDataTip">

              2)
              private function formatDataTip(hitData:HitData):String{

              return "Total: "+ hitData.item.NameOfSeriesHere;
              }

              Now, I'll warn you ahead of time, that the name of the "NameOfSeriesHere" item you want to display - that actual value, works a little depending on the type of series you are using - specifically, pie chart vs. all the others. So, debug your app, watch the "hitData" variable and determine what variables you want to use.

              The Flex 2 developers guide is a great resource also.

              Cheers,

              David
