Hi ,

What I can to do is to have on the same plot , a part in dotted then plain line then again dotted Your solution make only a dotted graph.

Here is the sample

Hello eltorfuerte,

You could add a new Line series and extend our IF condition in the FillSceneGraph event. Please take a look at the attached sample for more details and let me know if you have any questions.

Regards

Hi Actually I have a an extra question : I changed your sample in order to have 2 lineSeries. What I want is to applied the dotted lines on only one lineserie. The other have to stay continuous (no dotted lines).

Do you know how I can do that ?

Hello Eltorfuerte,

Please take a look at the modification that I made in the code:

private void ultraChart1_FillSceneGraph(object sender, Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs e)
        {
            List<Polyline> originals = new List<Polyline>();
            List<Polyline> fisrtStageLsit = new List<Polyline>();

            foreach (Primitive pr in e.SceneGraph)
            {
                if (pr.GetType() == typeof(Polyline))
                {
                    DataPoint[] dtpFirstStage = new DataPoint[((Polyline)pr).points.Count()];
                    int j=0,k = 0;
                    foreach (DataPoint dp in ((Polyline)pr).points)
                    {
                        originals.Add((Polyline)pr);
                        if (k > 1 && k < 6) { dtpFirstStage[j] = dp; j++; }
                        k++;

                    }
                    ((Polyline)pr).lineStyle.DrawStyle = LineDrawStyle.Dot;
                    ((Polyline)pr).PE.Fill = Color.Yellow;
                    ((Polyline)pr).PE.StrokeWidth = 3;

                    Polyline fisrtStage = new Polyline(dtpFirstStage);
                    fisrtStage.PE.Fill = Color.LightBlue;
                    fisrtStage.PE.StrokeWidth = 4;
                    fisrtStage.lineStyle.DrawStyle = LineDrawStyle.Solid;

                    fisrtStageLsit.Add(fisrtStage);
                }
            }
            if (fisrtStageLsit.Count > 0)
            {
                foreach (Primitive item in fisrtStageLsit) e.SceneGraph.Add(item);
            }

        }

Here is the result:

Hi ,

I don't really understand what you mean by modify the drawstyle , in your sample  eeI tried this :

        private void ultraChart1_FillSceneGraph(object sender, Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs e)
        {
            List<Polyline> originals = new List<Polyline>();
            List<Polyline> fisrtStageLsit = new List<Polyline>();

            foreach (Primitive pr in e.SceneGraph)
            {
                if (pr.GetType() == typeof(Polyline))
                {
                    DataPoint[] dtpFirstStage = new DataPoint[((Polyline)pr).points.Count()];
                    int k = 0;
                    foreach (DataPoint dp in ((Polyline)pr).points)
                    {
                        originals.Add((Polyline)pr);
                        if (k < 2 && k >5 ) dtpFirstStage[k] = dp;
                        k++;

                    }
                    ((Polyline)pr).lineStyle.DrawStyle = LineDrawStyle.Dot;
                    ((Polyline)pr).PE.Fill = Color.Yellow;
                    ((Polyline)pr).PE.StrokeWidth = 3;

                    Polyline fisrtStage = new Polyline(dtpFirstStage);
                    fisrtStage.PE.Fill = Color.LightBlue;
                    fisrtStage.PE.StrokeWidth = 4;
                    fisrtStage.lineStyle.DrawStyle = LineDrawStyle.Solid;

                    fisrtStageLsit.Add(fisrtStage);
                }
            }
            if (fisrtStageLsit.Count > 0)
            {
                foreach (Primitive item in fisrtStageLsit) e.SceneGraph.Add(item);
            }

        }

so what i want to see is a solid line between point nb 2 and 5 but what I have is just a dotted line.

Can you tell me what is wrong please ?

Thanks
