Convert Chart object to Image object C#

Question

I want to convert a chart object to a Image object, or if it is not possible then save the chart to a .jpg file. I need this because I want the chart put in to a PDFSharp object..

So this is my sample code so far:

Chart chart1 = new Chart();

            chart1.Series.Add("series1");
            chart1.Series.Add("series2");
            chart1.Series.Add("series3");

            chart1.Series["series1"].ChartType = SeriesChartType.Column;
            chart1.Series["series2"].ChartType = SeriesChartType.Line;
            chart1.Series["series3"].ChartType = SeriesChartType.Area;

            Random random = new Random();

            for (int pointIndex = 0; pointIndex < 10; pointIndex++)
            {

                chart1.Series["series1"].Points.AddY(random.Next(20, 50));
            }

            for (int pointIndex = 0; pointIndex < 10; pointIndex++)
            {

                chart1.Series["series2"].Points.AddY(random.Next(50, 100));
            }

            for (int pointIndex = 0; pointIndex < 10; pointIndex++)
            {

                chart1.Series["series3"].Points.AddY(random.Next(70, 100));
            }

            chart1.SaveImage(@".\test", ImageFormat.Jpeg);

Because of a reason i dont know the 'chart1.SaveImage(@".\test", ImageFormat.Jpeg);' puts out a empty file

Related tip: If your char doesn't happen to contain full-color photographs, you really should be using PNG for your chart; you'll get a smaller file without the quality loss — cbr, Jun 18 '15 at 07:50
thank you for the hint but i get a only a white image without any chart graphics — Artur Karaev, Jun 18 '15 at 08:03
@cubrr you mean (@".\test.Jpeg", ImageFormat.Jpeg) ? I also tried this — Artur Karaev, Jun 18 '15 at 08:12
@cubr, I made step forward looks like I forget to define height and width when I have done this I will answer — Artur Karaev, Jun 18 '15 at 09:03

This post is about f-sharp but i think you could have the same problem. FSharpChart.SaveAs () saves blank image if called before chart rendering is complete

it looks like that the chart first have to be displayed before you can save it.
