Property Value

Type Description

A string that is the text pattern.


The RangeSegmentColorizer.RangeStops collection neighbor values form the start and end values for the colorizer legend items.

The LegendItemPattern can contain regular text (displayed as is) and value placeholders in braces. To format numeric values, you can apply Format Specifiers. Use a colon to separate a placeholder and its format specifier.

The following table contains the available placeholders:

Placeholder Description
{V1} Displays the start range value.
{V2} Displays the end range value.


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:

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;
