Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v26.1.dll

NuGet Package: DevExpress.Charts

Declaration

C#

[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
public SegmentColorizerBase SegmentColorizer { get; set; }

VB.NET

<XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)>
Public Property SegmentColorizer As SegmentColorizerBase

Property Value

Type	Description
SegmentColorizerBase	The SegmentColorizerBase descendant.

Remarks

The Chart control provides the following colorizers you can use to color line segments:

• PointBasedSegmentColorizer
• RangeSegmentColorizer
• TrendSegmentColorizer

Simultaneously, with a segment colorizer, you can use a Point Colorizer to color the line series markers.

Example

This example demonstrates how to use the RangeSegmentColorizer to color a line series by its segments.

Follow the steps below to configure the RangeSegmentColorizer object and apply it to a line series view:

• Create a RangeSegmentColorizer instance and assign it to the LineSeriesView.SegmentColorizer property.

• Populate the RangeSegmentColorizer.RangeStops collection.

• Use the RangeSegmentColorizer.Palette property to define a palette.

• The RangeSegmentColorizer.LegendItemPattern property allows you to specify how to format text the legend shows for each color range.

C#

RangeSegmentColorizer colorizer = new RangeSegmentColorizer();
colorizer.RangeStops.AddRange(new double[] { -40, -35, -30, -25, -20, -15, -10, -5, 0, 5, 10, 15, 20, 25, 30 });
colorizer.Palette = new Palette("TemperaturePalette", new PaletteEntry[] { new PaletteEntry(Color.DarkBlue),
                                                                           new PaletteEntry(Color.SteelBlue),
                                                                           new PaletteEntry(Color.LightBlue),
                                                                           new PaletteEntry(Color.Yellow),
                                                                           new PaletteEntry(Color.OrangeRed) });
// Alternatively, you can use PaletteName to specify a palette.
// colorizer.PaletteName = Palettes.Slipstream.DisplayName;
colorizer.ShowInLegend = true;
colorizer.LegendItemPattern = "{V1:F0}°C — {V2:F0}°C";
LineSeriesView lineSeriesView = chartControl.Series[0].View as LineSeriesView;
lineSeriesView.SegmentColorizer = colorizer;

VB.NET

Dim colorizer As RangeSegmentColorizer = New RangeSegmentColorizer
colorizer.RangeStops.AddRange(New Double() {-40, -35, -30, -25, -20, -15, -10, -5, 0, 5, 10, 15, 20, 25, 30})
colorizer.Palette = New Palette("TemperaturePalette", New PaletteEntry() { New PaletteEntry(Color.DarkBlue), 
                                                                           New PaletteEntry(Color.SteelBlue), 
                                                                           New PaletteEntry(Color.LightBlue), 
                                                                           New PaletteEntry(Color.Yellow), 
                                                                           New PaletteEntry(Color.OrangeRed)})
' Alternatively, you can use PaletteName to specify a palette.

colorizer.ShowInLegend = true
colorizer.LegendItemPattern = "{V1:F0}°C — {V2:F0}°C"
Dim lineSeriesView As LineSeriesView = CType(chartControl.Series(0).View,LineSeriesView)
lineSeriesView.SegmentColorizer = colorizer
