Matt,
Here is the code for the LineSeries if hard-coded to chart one
selectedItem at a time from the dataGrid:
<mx:LineSeries name="{Deposits.selectedItem.CATEGORY}"
xField="SCHEDDATE" yField="TOTALBAL"
showDataEffect="drillDownEffect">
*Deposits is the name of the dataGrid
When using this code, I attach the event
change="webservice1.PulseGraphLoanByCategory.send()" to the
dataGrid.
When trying to use the addSeries function, I remove that event
handler and replace with change="addSeries()" and place the call to
the WS method in the addSeries script. That is one thing I'm not
sure about. Here is the addSeries script:
function addSeries() {
webservice1.PulseGraphShareByCategory.send()
linechartDeposits.series.removeAll();
for (var i=0; i<Deposits.selectedIndices.length; i++) {
var ls=new LineSeries();
ls.yField=Deposits.selectedItems[i].TOTALBAL;
ls.xField=Deposits.selectedItems[i].SCHEDDATE;
ls.name=Deposits.selectedItems[i].CATEGORY;
linechartDeposits.series.addItem(ls);
}
}
ALSO - the name field comes back defined (in the dataTips) but the
yField and xField are undefined.
Any help would be greatly appreciated!
