Hi ,
I want to plot a splinechart like dotted-plain line- plotted. I found in an a previous discussion something like :
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 < 4) 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); } }
This works but only for line dotted , how can i do dotted-line-dotted ?
Thanks
Hello Eltorfuerte,
I suppose that you refer my previous forum thread: http://ko.infragistics.com/community/forums/t/74479.aspx . If so, I think that your scenario is different, and mentioned approach from that forum thread is not suitable.
My suggestion is to use LineAppearance and SplineChartAppearance to modify your lines in the chart. For example:
LineAppearance la = new LineAppearance();
la.LineStyle.DrawStyle = LineDrawStyle.Dot;
la.Thickness = 5;
SplineChartAppearance sca = new SplineChartAppearance();
sca.LineAppearances.Add(la);
myColumnLayer.ChartTypeAppearance = sca;
Let me know if you have any questions.
Regards
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.
OK. I misunderstand your requirements. In that case, you should use the mentioned approach form another forum thread. I already try this and everything works properly. Just change the DrawStyle. If you still have a problems with that, pleaseupload your sample and I`ll be glad to research it for you.
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 ?
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 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,
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.
