using DevExpress.XtraCharts;
using DevExpress.XtraCharts.Heatmap;
using System;
using System.Drawing;
using System.Windows.Forms;

namespace HeatmapMatrixAdapterSample {

            this.Controls.Add(heatmap);

            heatmap.Dock = DockStyle.Fill;

            HeatmapMatrixAdapter dataAdapter = new HeatmapMatrixAdapter();
            dataAdapter.XArguments = new string[] { "North", "South", "West", "East", "Central" };
            dataAdapter.YArguments = new string[] { "Components", "Clothing", "Bikes", "Accessories" };
            dataAdapter.Values = new double[,] {

            RangeColorProvider colorProvider = new RangeColorProvider() { Palette = palette, ApproximateColors = true };
            colorProvider.RangeStops.Add(new Unit(0, UnitType.Percentage));

            dataAdapter.ColorProvider = colorProvider;

            HeatmapLabel label = heatmap.Label;
            label.Visible = true;
            label.Pattern = "{V:f0}";
            label.BackColor = Color.White;
            label.Color = Color.Black;
            label.DXFont = new DXFont("SegoeUI", 10);
            label.TextOrientation = HeatmapTextOrientation.Horizontal;
            label.Border.Visibility = DefaultBoolean.True;
            label.Border.Color = Color.DarkGray;
            label.Border.Thickness = 2;
        }
