ChartDirector是一款支持多种开发语言和开发平台的图表控件，可以用于WinForm和WebForm，支持多种常用的工业图表类型和金融图表类型，其中蜡烛图是金融和股票上应用最广泛的，这篇文章主要介绍如何使用ChartDirector创建一个蜡烛图，具体可以参考下面的代码：

using System;
using ChartDirector;

namespace CSharpChartExplorer
{
    public class hloc : DemoModule
    {
        //Name of demo module
        public string getName() { return "Simple HLOC Chart"; }

        //Number of charts produced in this demo module
        public int getNoOfCharts() { return 1; }

        //Main code for creating chart.
        //Note: the argument chartIndex is unused because this demo only has 1 chart.
        public void createChart(WinChartViewer viewer, int chartIndex)
        {
            //
            // Sample data for the HLOC chart.
            //
            double[] highData = {2043, 2039, 2076, 2064, 2048, 2058, 2070, 2033, 2027, 2029, 2071,
                2085, 2034, 2031, 2056, 2128, 2180, 2183, 2192, 2213, 2230, 2281, 2272};

            double[] lowData = {1931, 1921, 1985, 2028, 1986, 1994, 1999, 1958, 1943, 1944, 1962,
                2011, 1975, 1962, 1928, 2059, 2112, 2103, 2151, 2127, 2123, 2152, 2212};

            double[] openData = {2000, 1957, 1993, 2037, 2018, 2021, 2045, 2009, 1959, 1985, 2008,
                2048, 2006, 2010, 1971, 2080, 2116, 2137, 2170, 2172, 2171, 2191, 2240};

            double[] closeData = {1950, 1991, 2026, 2029, 2004, 2053, 2011, 1962, 1987, 2019, 2040,
                2016, 1996, 1985, 2006, 2113, 2142, 2167, 2158, 2201, 2188, 2231, 2242};

            // The labels for the HLOC chart
            string[] labels = {"Mon 1", "Tue 2", "Wed 3", "Thu 4", "Fri 5", "Mon 8", "Tue 9",
                "Wed 10", "Thu 11", "Fri 12", "Mon 15", "Tue 16", "Wed 17", "Thu 18", "Fri 19",
                "Mon 22", "Tue 23", "Wed 24", "Thu 25", "Fri 26", "Mon 29", "Tue 30", "Wed 31"};

            // Create a XYChart object of size 600 x 350 pixels
            XYChart c = new XYChart(600, 350);

            // Set the plotarea at (50, 25) and of size 500 x 250 pixels. Enable both the horizontal
            // and vertical grids by setting their colors to grey (0xc0c0c0)
            c.setPlotArea(50, 25, 500, 250).setGridColor(0xc0c0c0, 0xc0c0c0);

            // Add a title to the chart
            c.addTitle("Universal Stock Index on Jan 2001");

            // Add a custom text at (50, 25) (the upper left corner of the plotarea). Use 12pt Arial
            // Bold/blue (4040c0) as the font.
            c.addText(50, 25, "(c) Global XYZ ABC Company", "Arial Bold", 12, 0x4040c0);

            // Add a title to the x axis
            c.xAxis().setTitle("Jan 2001");

            // Set the labels on the x axis. Rotate the labels by 45 degrees.
            c.xAxis().setLabels(labels).setFontAngle(45);

            // Add a title to the y axis
            c.yAxis().setTitle("Universal Stock Index");

            // Draw the y axis on the right hand side of the plot area
            c.setYAxisOnRight(true);

            // Add a HLOC layer to the chart using green (008000) for up days and red (ff0000) for
            // down days
            HLOCLayer layer = c.addHLOCLayer3(highData, lowData, openData, closeData, 0x008000,
                0xff0000);

            // Set the line width to 2 pixels
            layer.setLineWidth(2);

            // Output the chart
            viewer.Chart = c;

            //include tool tip for the chart
            viewer.ImageMap = c.getHTMLImageMap("clickable", "",
                "title='{xLabel} Jan 2001\nHigh:{high}\nOpen:{open}\nClose:{close}\nLow:{low}'");
        }
    }
