C#

public void chart()
    {
        SqlConnection con = new SqlConnection(gps_conn);
        con.Open();
        string query = "select time_stamp,sensor2_1 from imei_352848026619078 where time_stamp between '"+fromtxt.Text+"' and '"+totxt.Text+"' order by time_stamp asc";
        SqlDataAdapter da = new SqlDataAdapter(query, con);
        DataSet ds = new DataSet();
        da.Fill(ds);
        Chart1.DataSource = da;
        Chart1.ChartAreas["ChartArea1"].AxisX.Title = "Time_stamp";
        Chart1.ChartAreas["ChartArea1"].AxisY.Title="Liters";
        Chart1.Series["Series1"].XValueMember = "time_stamp";
        Chart1.Series["Series1"].YValueMembers = "sensor2_1";
        Chart1.DataBind();
        da.Dispose();
        con.Close();
    }

I wrote above code to bind data to chart. But data is not binding to chart. Please improve the above code and give me the solution.

Hi, dost...

public void chart()
{
SqlConnection con = new SqlConnection(gps_conn);
con.Open();
string query = "select time_stamp,sensor2_1 from imei_352848026619078 where time_stamp between '"+fromtxt.Text+"' and '"+totxt.Text+"' order by time_stamp asc";
SqlDataAdapter da = new SqlDataAdapter(query, con);
DataSet ds = new DataSet();
da.Fill(ds);
Chart1.DataSource = ds.Tables[0];// here, you need to use it( ds.Tables[0]) instead of da.
Chart1.ChartAreas["ChartArea1"].AxisX.Title = "Time_stamp";
Chart1.ChartAreas["ChartArea1"].AxisY.Title="Liters";
Chart1.Series["Series1"].XValueMember = "time_stamp";
Chart1.Series["Series1"].YValueMembers = "sensor2_1";
Chart1.DataBind();
da.Dispose();
con.Close();
}
