hello Member 11305067352,
below is ur code in c# language,i think this will help your problem.

protected void Button1_Click(object sender, System.EventArgs e)
{
    DataSet ds = new DataSet();
    //Read xml data to the dataset
    ds.ReadXml("YourXMLDocPath in .xml format");
    //code used for verifying necessary strings
    //Response.Write(ds.Tables(0).Columns(0).ColumnName.ToString())
    //Response.Write(ds.Tables(0).Columns(1).ColumnName.ToString())
    /*Here you can put your logic for top 5 score as per condition(use lamda expression on dataset for filtering your data),*/
    YourChart.DataSource = ds;
    YourChart.Series("Series1").XValueMember = ds.Tables(0).Columns(1).ColumnName.ToString();
    YourChart.Series("Series1").YValueMembers = ds.Tables(0).Columns(2).ColumnName.ToString();
    YourChart.Series.Add("Series2");
    YourChart.Series("Series2").XValueMember = ds.Tables(0).Columns(1).ColumnName.ToString();
    YourChart.Series("Series2").YValueMembers = ds.Tables(0).Columns(3).ColumnName.ToString();
    YourChart.Series(0).Color = Drawing.Color.Red;
    YourChart.Series(1).Color = Drawing.Color.Blue;
    YourChart.ChartAreas("ChartArea1").AxisX.Interval = 1;
    YourChart.DataBind();
