Hi!

I am using Zedgraph in my ASP.NET application. I want to remove duplicate legend in my graph. Please help!

Here's my code:

//Default.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Drawing;
using ZedGraph;
using System.Configuration;
using System.Data;
// using System.Data.SQLite;

public partial class _Default : System.Web.UI.Page
{

    protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
           
            this.ZedGraphWeb1.RenderGraph += new ZedGraph.Web.ZedGraphWebControlEventHandler(this.OnRenderGraph1);

        
            if (!IsPostBack)
            {
                lblDateTime.Text = DateTime.Now.ToString();

                string SQLiteQuery = "SELECT BatteryName FROM Battery";

                DatabaseConnection ConnectionDatabase = new DatabaseConnection();
                DataSet DatSet = ConnectionDatabase.GetDataSet(SQLiteQuery);

                DataTable DatTable = DatSet.Tables[0];

                if (DatTable.Rows[0].IsNull(0) == false)
                {
                    lblBattery.Text = Convert.ToString(DatSet.Tables[0].Rows[0][0]);
                }
            }
        }
        catch (Exception ex)
        {
            string Error = ex.ToString();
        }
    }

    List<double> XList;
    List<double> YList;

    private PointPairList GetPointPairList()
    {
        PointPairList list = new PointPairList();

        try
        {
              //string SQLiteQuery = "SELECT bp.PowerTime As DateTime, bp.PowerValue As Power ";
            //SQLiteQuery += "FROM BatteryPower bp ";
            //SQLiteQuery += "ORDER BY bp.PowerTime DESC;";

            //DatabaseConnection ConnectionDatabase = new DatabaseConnection();
            //DataSet DatSet = ConnectionDatabase.GetDataSet(SQLiteQuery);
    
            //DataTable DatTable = DatSet.Tables[0];

            //double x = 0.0D;
            //double y = 0.0D;

            //DateTime dt = new DateTime();

           
            //for (int i = 0; i < DatTable.Rows.Count; i++)
            //{

            //    {

            //        list.Add(x, y);
            //    }
            //}
