由于项目的需要，试用了几个公司的图表控件，比如Dundas Chart，但是都觉得软件庞大，虽然功能也很强大，但是使用起来比较复杂，有很多功能实际用不上。

后来试用了ChartFX，感觉不错，区区几行代码就可以Show出图表，以下是我写的一个例子：

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using  SoftwareFX.ChartFX.Lite;

namespace ChartTest
{
    /**//// <summary>
    /// Form1 的摘要说明。
    /// </summary>
    public class Form1 : System.Windows.Forms.Form
    {
        private SoftwareFX.ChartFX.Lite.Chart chart1;
        private System.Windows.Forms.ComboBox comboBox1;
        private System.Windows.Forms.CheckBox checkBox1;
        /**//// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.Container components = null;

        public Form1()
        {
            //
            // Windows 窗体设计器支持所必需的
            //
            InitializeComponent();

            //
            // TODO: 在 InitializeComponent 调用后添加任何构造函数代码
            //
        }

        /**//// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        protected override void Dispose( bool disposing )
        {
            if( disposing )
            {
                if (components != null) 
                {
                    components.Dispose();
                }
            }
            base.Dispose( disposing );
        }
