I want to create chart by commands to put it in loop later, but it failed!

I tried this:

Chart Chr = new Chart();
	Chr.ID = "chr1";

        Chr.Series.Add("Age");
        Chr.Series["Age"].Points.AddXY("Max", 33);
        Chr.Series["Age"].Points.AddXY("Xam", 50);
        Chr.Series["Age"].Points.AddXY("Nax", 20);
        Chr.Series["Age"].Points.AddXY("Xan", 80);
		
        Chr.Width = 500;

        Panel1.Controls.Add(Chr);

It's run.. but it shows nothing!
It take space on the page, but blank space..

Aftar that, I made these changes:

Chart Chr = new Chart();

        Chr = new Chart();

        Chr.ID = "chr2";
        Chr.ImageLocation = "ChartPic_#SEQ(300,3)";

        Chr.Series.Add("Ageq");

        Chr.Series["Ageq"].ChartType = SeriesChartType.Pie;
        Chr.Series["Ageq"].Palette = ChartColorPalette.Berry;

        Chr.Series["Ageq"].BackImage = "ChartPic_#SEQ(300,3)";
      
        Chr.Series["Ageq"].Points.AddXY("Maxq", 11);
        Chr.Series["Ageq"].Points.AddXY("Xamq", 22);
        Chr.Series["Ageq"].Points.AddXY("Naxq", 55);
        Chr.Series["Ageq"].Points.AddXY("Xanq", 44);

        Chr.Width = 600;

        Chr.Height = 100;

        Chr.Palette = ChartColorPalette.Berry;

        Chr.Visible = true;
      
        Panel1.Controls.Add(Chr);

It gave me the same result..
It's run.. but it shows nothing!

That's right!
Thank you it worked..

I've done 3 little changes on the code to run on the right way..

        ChartArea chartArea1 = new ChartArea();
        Legend legend1 = new Legend();

        Series series1 = new Series();

        Chart Chr = new Chart();

        Chr = new Chart();

Chr.ID = "chr2";

        Chr.ChartAreas.Add(chartArea1);
        legend1.Name = "Legend1";
        Chr.Legends.Add(legend1);

        Chr.Series.Add("Ageq");

        Chr.Series["Ageq"].ChartType = SeriesChartType.Pie;
        Chr.Series["Ageq"].Palette = ChartColorPalette.Berry;

        Chr.Series["Ageq"].Points.AddXY("Maxq", 11);
        Chr.Series["Ageq"].Points.AddXY("Xamq", 22);
        Chr.Series["Ageq"].Points.AddXY("Naxq", 55);
        Chr.Series["Ageq"].Points.AddXY("Xanq", 44);

Chr.Width = 500;
           
        Chr.Palette = ChartColorPalette.Berry;

        Chr.Visible = true;

Panel1.Controls.Add(Chr);

Thank you again..

You are missing Series.ChartArea Property and Legend Property

Here i have done some modifications to your code

C#

ChartArea chartArea1 = new ChartArea();
           Legend legend1 = new Legend();

           Series series1 = new Series();

           Chart Chr = new Chart();

           Chr = new Chart();

           Chr.Name = "chr2";

           Chr.ChartAreas.Add(chartArea1);
           legend1.Name = "Legend1";
           Chr.Legends.Add(legend1);

           Chr.Series.Add("Ageq");

           Chr.Series["Ageq"].ChartType = SeriesChartType.Pie;
           Chr.Series["Ageq"].Palette = ChartColorPalette.Berry;

           Chr.Series["Ageq"].Points.AddXY("Maxq", 11);
           Chr.Series["Ageq"].Points.AddXY("Xamq", 22);
           Chr.Series["Ageq"].Points.AddXY("Naxq", 55);
           Chr.Series["Ageq"].Points.AddXY("Xanq", 44);

           Chr.Size = new System.Drawing.Size(559, 418);

           Chr.Palette = ChartColorPalette.Berry;

           Chr.Visible = true;

           panel1.Controls.Add(Chr);
