MSChart: line chart UI does not look proper

I was trying to generate winform line chart from data table but UI does not look good.

see the UI

enter image description here

also see my full sample code. I believe I am missing something in code for which chart UI does not look good. I do not understand for what reason a white box is coming in chart?

please see my full code and tell me what I need to add or rectify in my code.

code

   private void show()
        {
            DataRow dr = null;
            DataTable dt = new DataTable();
            dt.Columns.Add("Date", typeof(DateTime));
            dt.Columns.Add("data", typeof(Int32));
            dt.Columns.Add("CountryCode", typeof(string));

            dr = dt.NewRow();
            dr[0] = DateTime.Parse("01/01/2017");
            dr[1] = 03;
            dr[2] = "GB";
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr[0] = DateTime.Parse("02/01/2017");
            dr[1] = 09;
            dr[2] = "GB";
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr[0] = DateTime.Parse("03/01/2017");
            dr[1] = 15;

issue solved. this line causing problem Chart1.ChartAreas.Add("chtArea"); so i removed this line.

my fresh code

    private void show()
    {
        DataRow dr = null;
        DataTable dt = new DataTable();
        dt.Columns.Add("Date", typeof(DateTime));
        dt.Columns.Add("data", typeof(Int32));
        dt.Columns.Add("CountryCode", typeof(string));

        dr = dt.NewRow();
        dr[0] = DateTime.Parse("01/01/2017");
        dr[1] = 30;
        dr[2] = "GB";
        dt.Rows.Add(dr);

        dr = dt.NewRow();
        dr[0] = DateTime.Parse("02/01/2017");
        dr[1] = 09;
        dr[2] = "GB";
        dt.Rows.Add(dr);

        dr = dt.NewRow();

A Chart comes with a few default elements, like a ChartArea, a Series and a Legend.

If you want to create a ChartArea of your own, why not clear the default ChartArea first? Chart1.ChartAreas.Clear(); Then (and only then) your will actually access your newly created one with the Chart1.ChartAreas[0] references.

I also suggest to use short and nicely named references to Series, ChartAreas etc..:

ChartArea chtArea = Chart1.ChartAreas.Add("chtArea");

Series unitPrice = Chart1.Series.Add("UnitPrice");

This makes the code more compact and clearer..
