• [z]如何C#编程显示K线图


    如果自己开发行情软件,如何方便地呈现K线?
    最麻烦的办法就是用GDI+等方法自己绘制,国内的行情软件(例如通达信、大智慧)大多是这样开发的。
    但是这对于个人来说不论从开发周期上还是技术上都是不可取的。
    最简单快捷的方法就是用第三方组件,例如MicrosoftChar,ZedGragh,StockChartX等。
    下面我介绍如何基于StockChartX显示K线。
    1、将ModulusFE.StockChartX.dll添加到项目引用中

    2、定义K线数据类
    public class BarData
        {
            public DateTime Date; 
            public double OpenPrice;
            public double HighPrice;
            public double LowPrice;
            public double ClosePrice;
            public double Volume;
        }
    3、声明图表实例
    private readonly StockChartX _stockChartX;
    4、从文件中读取数据,装载入K线数据List
     private void LoadData(string fileName)
            {
                Data.Clear();
                #region
                try
                {
                    using (FileStream fs = new FileStream(AppDomain.CurrentDomain.BaseDirectory + fileName, FileMode.Open))
                    {
                        using (StreamReader sr = new StreamReader(fs))
                        {
                            sr.BaseStream.Seek(0, SeekOrigin.Begin);
                            while (sr.Peek() > -1)
                            {
                                string[] record = sr.ReadLine().Split(new[] { ',' });
                                string[] date = record[0].Split('/');
                                BarData bar = new BarData
                                {
                                    Date = new DateTime(int.Parse(date[2]), int.Parse(date[0]), int.Parse(date[1])),
                                    OpenPrice = Double.Parse(record[1], CultureInfo.InvariantCulture),
                                    HighPrice = Double.Parse(record[2], CultureInfo.InvariantCulture),
                                    LowPrice = Double.Parse(record[3], CultureInfo.InvariantCulture),
                                    ClosePrice = Double.Parse(record[4], CultureInfo.InvariantCulture),
                                    Volume = Double.Parse(record[5], CultureInfo.InvariantCulture) / 1000000
                                };
                                Data.Add(bar);
                            }
                        }
                    }
                }
                catch
                {
                    return;
                }
                #endregion
            }
    5、刷新K线图
    public void RefreshChart()
            {
                _currentBar = (int)(Data.Count * 0.75);
                for (Row = 0; Row < _currentBar; Row++)
                {
                    BarData bd = Data[Row];
                    _stockChartX.AppendOHLCValues(_stockChartX.Symbol, bd.Date, bd.OpenPrice, bd.HighPrice, bd.LowPrice, bd.ClosePrice);
                    _stockChartX.AppendVolumue(_stockChartX.Symbol, bd.Date, bd.Volume);
                }
                _stockChartX.Update();
            }
