Hi

How to clear all the data when second time loading using asp.net and C#.Now I am getting same value again in graph

//string personal=count1.ToString()+","+count2.ToString()+","+count3.ToString()+","+count
4.ToString()+","+count5.ToString();
BarChart1.BarType = MindFusion.Charting.BarType.Clustered3D;
/* clear the predefined data */
BarChart1.XData.Clear();
BarChart1.YData.Clear();
//BarChart1.ClearData();  ("This line gives error object Ref not set" ();

//BarChart1.Data.Clear();
/* set the X, Y and Y2 data */


//int flag=int.Parse(Session["no"].ToString());

if (flag==0)
{
double[] k1 = {l1,l2,l3,l4,l5};
double[] r1 = {count1,count2,count3,count4,count5};

BarChart1.Data.Add( new ArrayList( r1));//personal, 120, 77,68
BarChart1.Data.Add( new ArrayList( k1));//Others, 73, 81,56
BarChart1.ClusterLabels = new string[]{"Cat1", "Cat2", "Cat3", "Cat4","Cat5"};

BarChart1.ClustLabelAlignment = StringAlignment.Center;
/* set the inner labels */
//ArrayList innerLabels =new ArrayList( new string[]{"Jan", "February", "March", "April"} );
//BarChart1.InnerLabels.Add( innerLabels );
//BarChart1.InnerLabels.Add( innerLabels );
//BarChart1.InnerLabels.Add( innerLabels );
