Is it possible to add chart legend as a seperate custom component in flex?

Question

Im trying to add legend as a seperate component in flex charts. Actually my intention is , when user select item from legend .. corresponding chart item should be highlighted . Is this possible ?

Answer 1

It is possible. You just need to add an event listener to the legend and highlight the corresponding chart item on the event handler.

// Assign an id to each legend item
<mx:LegendItem id="yourLegendItem" label="Your Label">

// Add a mouse click event listener to it
yourLegendItem.addEventListener(MouseEvent.CLICK, highlightYourChartItem);

// Handle the mouse clicks
function highlightYourChartItem(event:MouseEvent):void
{
  // Code to highlight the item. You can add a glow, change the color, etc
}
