用dotnetCHARTING 制作柱形图,折线图和圆饼图.doc

最近由于项目需要,要做几个统计图. 网上找了找发现了ZedGraph控件和dotnetCHARTIN控件.ZedGraph:支持winform和webform。支持可视化设计,并且最主要他是开源的.dotnetCHARTIN:需要到网上找破解版的 下载地址:/xiaogangqq123/dotnetcharting.rar网上说dotnetCHARTIN这个控件比较耗费性能.并且支持二维和三维.ZedGraph控件开源.扩展性强,但是只支持二维图形.性能较好.由于项目需要三维的 所以选择了dotnetCHARTIN这个.通过几次反复测试.感觉dotnetCHARTIN性能还行.当然是在理想情况下.由于网上dotnetCHARTIN资料较少.看了下帮助文档.自己做了个Demo分别对10条线一万条数据和10条10万条数据做了个初步测试.1万条:生成图片速度大概在2秒到5秒;10万条:速度估计在5秒-10秒之间 ，大体是这个样子.贴出代码:C#代码 public class Charting #region 共有变量 / / 图片存放路径 / public string PhaysicalImagePath get; set; / / 标题 / public string Title get; set; / / X轴名称 / public string XName get; set; / / Y轴名称 / public string YName get; set; / / 图例名称 / public string SeriseName get; set; / / 宽度 / public int SeriseWidth get; set; / / 高度 / public int SeriseHeight get; set; / / 数据源 / public DataTable DataSoure get; set; public bool IsUse3D get; set; public CharType type get; set; #endregion public Charting() / / 柱形图 / / public void CreateCombo(dotnetCHARTING.Chart Chart1) Chart1.Title = Title; Chart1.XAxis.Label.Text = XName; Chart1.YAxis.Label.Text = this.YName; Chart1.TempDirectory = this.PhaysicalImagePath; Chart1.Width = this.SeriseWidth; Chart1.Height = this.SeriseHeight; Chart1.Type = ChartType.Combo; Chart1.Series.Type = SeriesType.Cylinder; Chart1.Series.Name = this.SeriseName; Chart1.Series.Data = this.DataSoure; Chart1.SeriesCollection.Add(); Chart1.DefaultSeries.DefaultElement.ShowValue = true; Chart1.ShadingEffect = true; Chart1.Use3D = IsUse3D; Chart1.Series.DefaultElement.ShowValue = true; / / 饼图 / / public void CreatePie(dotnetCHARTING.Chart Chart1) Chart1.Title = Title; Chart1.XAxis.Label.Text = XName; Chart1.YAxis.Label.Text = this.YName; Chart1.TempDirectory = this.PhaysicalImagePath; Chart1.Width = this.SeriseWidth; Chart1.Height = this.SeriseHeight; Chart1.Type = ChartType.Pie; Chart1.Series.Type = SeriesType.Cylinder; Chart1.Series.Name = this.SeriseName; Chart1.ShadingEffect = true; Chart1.Use3D = IsUse3D; Chart1.DefaultSeries.DefaultElement.Transparency = 20; Chart1.DefaultSeries.DefaultElement.ShowValue = true; Chart1.PieLabelMode = PieLabelMode.Outside; Chart1.SeriesCollection.Add(getArrayData(); Chart1.Series.DefaultElement.ShowValue = true; private SeriesCollection getArrayData() SeriesCollection SC = new SeriesCollection(); DataTable dt = this.DataSoure; for (int i = 0; i dt.Rows.Count; i+) Series s = new Series(); s.Name = dt.Rowsi0.ToString(); Element e = new Element(); / 每元素的名称 e.Name = dt.Rowsi0.ToString(); / 每元素的大小数值 e.YValue = Convert.ToDouble(dt.Rowsi1.ToString(); s.Elements.Add(e); SC.Add(s); return SC; / / 曲线图 / / public void CreateLine(dotnetCHARTING.Chart Chart1) Chart1.Title = Title; Chart1.XAxis.Label.Text = XName; Chart1.YAxis.Label.Text = this.YName; Chart1.TempDirectory = this.PhaysicalImagePath; Chart1.Width = this.SeriseWidth; Chart1.Height = this.SeriseHeight; Chart1.Type = ChartType.Combo; /此处一定要用DefaultSeries.Type = SeriesType.Line 否则没效果 Chart1.DefaultSeries.Type = SeriesType.Line; Chart1.Series.Name = this.SeriseName; Chart1.Series.Data = this.DataSoure; Chart1.SeriesCollection.Add(); Chart1.DefaultSeries.DefaultElement.ShowValue = true; Chart1.ShadingEffect = false; Chart1.Use3D = IsUse3D; Chart1.Series.DefaultElement.ShowValue = true; 前台调用Code:代码 Charting ch = new Charting(); ch.Title = 统计; ch.XName = 国家; ch.YName = 数量(亿); ch.SeriseName = Num; ch.SeriseHeight = 500; ch.SeriseWidth = 1240; ch.PhaysicalImagePath = temp; ch.DataSoure = GetData.GetTablePie(); ch.IsUse3D = true; /创建图形，Chart1页面dotnetChartin的控件ID ch.Cre
