Public Class Heatmap 
   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" };
