Namespace: MindFusion.Charting.WinForms
Assembly: MindFusion.Charting.WinForms

 Syntax

C#

public class HeatmapChart : BiaxialChart

Visual Basic

Public Class HeatmapChart
    Inherits BiaxialChart

 Remarks

The heatmap accumulates intensity values and maps them (scaled to MaxIntensity) to the colors and positions listed in Colors gradient object. This class expects a series of at least three dimensions, where first and second values specify coordinates, and third one specifies intensity. Optional fourth dimension can return radius value per data point; if not provided, the control applies the DefaultRadius property value. The convenience HeatmapSeries class implements such 4-dimensional series by storing values in HeatmapPoint objects.
