Hi,

I need to set the line thickness of my line chart.

How do I do it?

Is there any property for setting the thickness of line graphs?

Hi,

Please use DataPoint.BorderWidth property for your requirement.

E.g.,

Chart c = new Chart();
   c.Height = 300;
   c.Width = 400;

   Series s = new Series();
   s.ChartType = ChartType.Line;
   s.DefaultDataPoint.BorderWidth = 7;
   s.DataPoints.Add(new DataPoint(1, 1));
   s.DataPoints.Add(new DataPoint(2, 2));
   s.DataPoints.Add(new DataPoint(3, 3));
   c.SeriesCollection.Add(s);

   //Save the chart image into a memory stream.
   MemoryStream ms = new MemoryStream();
   c.Save(ms, ImageFormat.Png);

   //Save the chart image from the memory stream to the response.
   Response.Clear();
   Response.ContentType = "image/png";
   Response.OutputStream.Write(ms.ToArray(), 0, (int) ms.Length);

Thank you.
