由于項目的需要，試用了幾個公司的圖表控件，比如Dundas Chart，但是都覺得軟件龐大，雖然功能也很強大，但是使用起來比較復雜，有很多功能實際用不上。

后來試用了ChartFX，感覺不錯，區區幾行代碼就可以Show出圖表，以下是我寫的一個例子：

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 的摘要說明。
    /// </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>
        /// 必需的設計器變量。
        /// </summary>
        private System.ComponentModel.Container components = null;

        public Form1()
        {
            //
            // Windows 窗體設計器支持所必需的
            //
            InitializeComponent();

            //
            // TODO: 在 InitializeComponent 調用后添加任何構造函數代碼
            //
        }

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