I have an area chart where one of the series (yellow) is in front and has larger values than another series (one on the bottom - supposed to be blue) and therefore completely hides it. If Yellow series hides both blue and green series you can't really tell which one is which because they both appear brownish. Is there any way to ensure that the largest series goes to the back or maybe change transparency values of the series so that they show up better?
You can make the colors transparent with:
this.ultraChart1.ColorModel.ModelStyle = Infragistics.UltraChart.Shared.Styles.ColorModels.CustomSkin;
PaintElement pe = new PaintElement(Color.Red);
pe.FillOpacity = 50;
this.ultraChart1.ColorModel.Skin.PEs.Add(pe);
pe = new PaintElement(Color.Green);
pe = new PaintElement(Color.Blue);
Also you can try using StackArea chart in your case.
