Hello,

I have to bind xml file to plot a graph using asp.net. I have used flowing code.

protected void btnBind_Click(object sender, EventArgs e)
{

string dataPath = MapPath(".") + "\\expense.xml";

DataSet ds = new DataSet();
ds.ReadXml(dataPath);
DataTable dt = ds.Tables[0];
DataView dv = new DataView(dt);
ChartExpense.Series[0].Points.DataBindXY(dv, "month", dv, "expense");
}

Now I want to plot the graph in some time interval using counter i.e. after every 5 secs the next value from xml file will be plot on graph. Please guide me through this.
