   Inherits C1.Win.Chart.Series

public class Heatmap : C1.Win.Chart.Series

Remarks

The heatmap series can use DataTable as data source. You can specify the list of column names (comma-separated) in BindingX property. If BindingX is not set the heatmap uses data from all columns with double data type.

Example

The following code creates heatmap series and add it to the chart.

var hmap = new Heatmap();
hmap.DataSource = new double [,] { { 0, 0.5 }, {0.5, 1 }, { 1, 0.4 }, { 0.5, 1 } };
hmap.ColorScale = new GradientColorScale() { Min = 0, Max = 1, Colors = new List<Color> { Color.White, Color.Red } };
chart.Series.Add(hmap);
chart.AxisX.DataSource = new string[] {"Q1", "Q2", "Q3", "Q4" };
chart.AxisY.DataSource = new string[] { "Region 1", "Region 2" };
