Wrong rendering of Doughnut Chart
posted

Hello all,

I am new to the Infragistics Charts and Documents.

I use folliowing libraries:
- .Net 4.0
- Infragistics NetAdvantage 2009.2

I created a DoughnutChart and can display it on my WinFormApp and I can export it to the PDF file.
The Data comes from DB.

Sometimes i get only one Data-Item to display/render.
Aslo DoughnutChart with only one row.

By displaying it on my WinFormApp there is no problem,
but if I render it to the PDF file the chart has wrong shape.

Here is my exsample code:

var chart = new UltraChart
                {
                   ChartType = ChartType.DoughnutChart,
                   Data = {DataSource =  new [] {42}}
                };
chart.Data.DataBind();

var report = new Report();
var section = report.AddSection();
var band = section.AddBand();
var canvas = band.AddCanvas();
canvas.Width = new FixedWidth(200);
canvas.Height = new FixedHeight(200);
var graphics = canvas.CreateGraphics();
chart.RenderPdfFriendlyGraphics(graphics, 200, 200);
try
{
   report.Publish("out.pdf", FileFormat.PDF);
  
   new Process{StartInfo = {FileName = "out.pdf"}}.Start();
}
catch (Exception ex)
{
   MessageBox.Show(ex.Message);
}


With this code I get following result:

 

I would like to have a round shape of my chart.

Thanks.

Best regards

    Hello Vaceslav,

    Could you please try this approach below:

     
    

    Report report = new Report();
    

    ISection section = report.AddSection();
    

    Infragistics.Documents.Reports.Graphics.Image image = new Infragistics.Documents.Reports.Graphics.Image(ultraChart1.Image);
    

    section.AddImage(image);
    

    report.Publish("..\\..\\Test.pdf", FileFormat.PDF);
    

    Process.Start("..\\..\\Test.pdf");

    and let me know if you have any questions.

    Regards
