hi
i am using combobox to change data in chart dynamically. In mouse event
of chart i am retrieving data-point using the below function.
onChartMouseMove(e:MouseEvent):void
{
var mouseOverData:Array =
chart.series[0].dataTransform.invertTransform(chart.mouseX, chart.mouseY)
}
while immediately moving the mouse over the chart. i am getting an error as
TypeError: Error #1009: Cannot access a property or method of a null object
reference.
