Hello,  
I write this code and trying to figure out why is that happening…  
the object mcDraw should follow the chart animation but he is going up too much  
and it appear to have an other line (circled in red) that shouldn’t be there!!!  
this is the code:

```auto

import com.greensock.TweenLite;

var startX:Number = 10;
var startY:Number = 200;
var chartHeight:Number = 190;
var pointInterval:Number = 50;

var chartData:Array = [71,123,54,211,46,187];

var myChart:Shape = new Shape();
var lineAnim:Shape = new Shape();
addChild(lineAnim);
addChild(myChart);

drawChart();

function drawChart():void
{
    //myChart.graphics.clear();
    lineAnim.graphics.clear();
    Yaxis.text = String(mcDraw.y);
    Xaxis.text = String(mcDraw.x);
    lineAnim.x = startX;
    lineAnim.y = startY;

    lineAnim.graphics.lineStyle(2, 0x333333);
    
    lineAnim.graphics.moveTo(0, 0);
    lineAnim.graphics.lineTo(0, -chartHeight);
    lineAnim.graphics.moveTo(0, 0);
    lineAnim.graphics.lineTo((chartData.length - 1) * pointInterval, 0);
    
    lineAnim.graphics.lineStyle(1, 0x0099FF);
    
        //lineAnim.graphics.lineStyle(1, 0x0099FF);
        //lineAnim.graphics.moveTo(mcDraw.x, mcDraw.y);
        

    for (var n:int = 0 ; n < chartData.length ; n++)
    {
        var thisHeight:Number = chartData[n] * chartHeight / maxVal(chartData);
    
        if (n == 0)
        {
            //myChart.graphics.moveTo(pointInterval * n, 0 - thisHeight);
            lineAnim.graphics.moveTo(pointInterval * n, 0 - thisHeight);
        }
    
        //myChart.graphics.lineTo(pointInterval * n, 0 - thisHeight);
        TweenLite.to(mcDraw, 1, {x:pointInterval * n, y:0 - thisHeight, delay:n*1, overwrite:false, onUpdate:updateHandler});
        lineAnim.graphics.endFill();
    }
    
    function updateHandler():void
    {
     lineAnim.graphics.lineTo(mcDraw.x, mcDraw.y);
     lineAnim.graphics.moveTo(mcDraw.x, mcDraw.y);
    }
}

function maxVal(givenArray):Number
{
    var max = givenArray[0];
    
    for (var m:int = 0; m<givenArray.length; m++)
    {
        
        if (givenArray[m] > max)
        {
            max = givenArray[m];
        }
    }
    return max;
}

```
