Moving markers

Question

In a cartesian chart, I have four series, three line and one
column series. I want to show moving markers on all of the four
series, when mouse is moved in chart region. Moving markers like
circle...
For that, I am using array of items which I have got through
items property of series object. and with the help of that array I
am getting x and y co-ordinates of each item.
I am then passing these co-ordinates to localToGlobal
function on series object to get global co-ordinates. After this, I
am getting the item with minimum diff between its co-ordinates and
the point where mouse is.
But the thing is, I am not getting exact item at the place,
where the mouse is. For whole width of an item on X-axis, i am
getting that item when the mouse is at the middle of that width.
Here is the sample code.....
var
arrSeries:Array=(ChartBase)(myPanel.getChildAt(1)).series;
for(var i:int=0;i<arrSeries.length;i++)
var arrItem:Array=arrSeries
.items;
var flag:int=-1;
var diff:int=100000000000;
for(var j:int=0;j<arrItem.length;j++)
arrItem[j].currentState="deselected";
for(var j:int=0;arrItem && j<arrItem.length;j++)
var p:Point =arrSeries.localToGlobal(new
Point(arrItem[j].x,arrItem[j].y));
if(diff>Math.abs(Math.ceil(p.x-event.currentTarget.mou*No
thank you*)))
diff=Math.abs(Math.ceil(p.x-event.currentTarget.mou*No thank
you*));
flag=j;
if(flag!=-1)
showValues(arrSeries
.yField,arrItem[flag]);
arrItem[flag].currentState="selected";

Answer 1

Yeah...get FCP 7. That feature was added to that upgrade. Other than that...you are stuck moving them manually.
