1) write a custom renderer for your columnseries. This renderer should
fill the columns with the standard color, _unless_ it's filling the
selected index. Something like this:
Class MyCustomRenderer
{
public var index:Number;
public var selectedIndex:Number;
function beginDraw(...)
{
index = 0;
}
function draw(...)
{
if (index == selectedindex)
{
// draw in selected color
}
else
{
// draw in normal color
}
index++;
}
}
Then set the selected index in a mouseOverData function:
<mx:ColumnChart
mouseOverData="event.hitData.element.renderer.selectedIndex =
event.hitData.index;event.hitData.element.invalidate()" >
<mx:series>
<mx:Array>
<mx:ColumnSeries>
<mx:renderer>
<MyCustomRenderer />
Or something to that effect.
2) not really possible in Flex 1.5.
Both of these are much more doable in Flex 2.
