Hey; i am trying ZedGraph in windows form. i imported the dll and it shows in UI designer successfully. when i compile and run the program. it pops up the zedgrah grilled view, but no points on it. could anyone help me see what was wrong?
using System;
using System.Collections.Generic;
using System.ComponentModel;

using System.Linq;
using System.Text;
using System.Windows.Forms;
using ZedGraph;

public partial class Form2 : Form

public Form2()
{
InitializeComponent();
}

{
CreateChart(zedGraphControl1);
}
public void CreateChart(ZedGraphControl zgc)
