a single pixel dashed line can often appear blurry due to anti-aliasing.  setting SmoothingMode=None on the chart will remedy this problem but may have some side effects like diagonal lines appearing pixelated.

This is a standard .net dash style and cannot be controlled. You can increase the thickness by setting PE.StrokeWidth on the box.

Hi

It works . Thanks. But please refer the attachment. The line is not clear as dashed(Small and thin). I need to increase the gap between lines but could not. I want it as clear dashed(Thick). Help me regarding this.

Thanks in advance.

you need to cast the primitive as a Box to set the line style.

Box box = p as Box;
if (box != null)
{
   box.lineStyle.DrawStyle = LineDrawStyle.Dash;
}

Also, the Row property value won't be at -2, you can omit that condition.

Hai

I used the following code in fillscenegraph event but dint get success. Can you please guide me to get the row=-2, column=1 as dotted line? Can you post the code to get this?

if (e.ChartCore.ChartType == ChartType.ColumnChart)
        {
            foreach (Primitive p in e.SceneGraph)
            {
                if (p.Path != null)
                {
                    if (p is Box && p.Row == -2 && p.Column == 1)
                    {
                        //To set the box fill as transparent

                        p.PE.Fill = System.Drawing.Color.Transparent;

                       /*I dont know code how to get dotted line*/
                     }

                }
            }

        }

Thanks in advance.
