Hello all,

My goal is to display my database table values ( I have two columns as Total and Used) on a pie chart. I used the WPFToolkit for the chart control and created a pie chart structure.

but I am stuck with binding the chart to the datasource.

Any one can pls suggest me a solution. Thanks !

This is what i have tried :

  public List<ram> getRamData()
            List<ram> list = new List<ram>();
            string query = "select top 1 Used,Total from UsageRam";
            cmd = new SqlCommand(query, con);
            dr = cmd.ExecuteReader();
            while (dr.Read())
                var reading = new ram
                    Used = Convert.ToInt32(dr[0]),
                    Total = dr[1].ToString()
