How to specify color to a Series derived legend.

[User (Old forums)]

#19183 |

I would like to control the colors used for specific value ranges; I have defined NumericScale custom steps and want to specify color for each range defined.  e.g. 95-100% = red.

<MeshSurfaceSeries instance

>.Legend.Mode = SeriesLegendMode.SeriesLogic;

 Can anyone help?

 Thanks,

Sam

No responses but eventually figured it out.

MeshSurfaceSeries meshSeries = (MeshSurfaceSeries)Chart.Series[0];
meshSeries.AutomaticPalette = false;
meshSeries.Palette.Add(0, Color.White);
meshSeries.Palette.Add(0, Color.Blue);
meshSeries.Palette.Add(25, Color.BlueViolet);
meshSeries.Palette.Add(50, Color.Purple);
meshSeries.Palette.Add(75, Color.YellowGreen);
meshSeries.Palette.Add(85, Color.Yellow);
meshSeries.Palette.Add(90, Color.Orange);
meshSeries.Palette.Add(95, Color.OrangeRed);
meshSeries.Palette.Add(100, Color.Red);

Companion snippet: set custom gridlines correlating to the above colors

Chart.Axis(StandardAxis.PrimaryY).NumericScale.MajorTickMode
    = Xceed.Chart.Core.MajorTickModeNumeric.IrregularSteps;
Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Clear();
Chart.Axis(StandardAxis.PrimaryY).NumericScale.Max = 100;

Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Add((double)25);// 25%
Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Add((double)25);// 50%
Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Add((double)25);//75
Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Add((double)10);//85
Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Add((double)05);//90
Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Add((double)05);//95
Chart.Axis(StandardAxis.PrimaryY).NumericScale.CustomSteps.Add((double)05);//100
