使用donetcharting可以很方便制作图表
引入dll，在页面放入控件
<dotnetCHARTING:Chart ID="Chart1" runat="server"> </dotnetCHARTING:Chart>
先写一个实体类，定义需要操作的变量
public class Charting { private string _phaysicalimagepath;//图片存放路径 private string _title; //图片标题 private string _xtitle;//图片x座标名称 private string _ytitle;//图片y座标名称 private string _seriesname;//图例名称 private int _picwidth;//图片宽度 private int _pichight;//图片高度 private MyChartType _type;//统计图类型(柱形,线形等) private bool _use3d;//是否显示成3维图片 private SeriesCollection _dt;//统计图数据源 private string _filename;//统计图片的名称(不包括后缀名) /**/ /// <summary> /// 图片存放路径 /// </summary> public string PhaysicalImagePath { set { _phaysicalimagepath = value; } get { return _phaysicalimagepath; } } /// <summary> /// 图片标题 /// </summary> public string Title { set { _title = value; } get { return _title; } } /**/ /// <summary> /// 图片x座标名称 /// </summary> public string XTitle { set { _xtitle = value; } get { return _xtitle; } } /**/ /// <summary> /// 图片y座标名称 /// </summary> public string YTitle { set { _ytitle = value; } get { return _ytitle; } } /**/ /// <summary> /// 图例名称 /// </summary> public string SeriesName { set { _seriesname = value; } get { return _seriesname; } } /// <summary> /// 图片宽度 /// </summary> public int PicWidth { set { _picwidth = value; } get { return _picwidth; } } /**/ /// <summary> /// 图片高度 /// </summary> public int PicHight { set { _pichight = value; } get { return _pichight; } } /// <summary> /// 统计图类型(柱形,线形等) /// </summary> public MyChartType Type { set { _type = value; } get { return _type; } } /// <summary> /// 是否将输出的图片显示成三维 /// </summary> public bool Use3D { set { _use3d = value; } get { return _use3d; } } /// <summary> /// 对比图形数据源 /// </summary> public SeriesCollection DataSource { set { _dt = value; } get { return _dt; } } /// <summary> /// 生成统计图片的名称 /// </summary> public string FileName { set { _filename = value; } get { return _filename; } } /// <summary> /// 生成统计图片 /// </summary> /// <param name="chart"></param> /// <param name="type">图形类别,如柱状，折线型</param> public void CreateStatisticPic(dotnetCHARTING.Chart chart) { chart.SeriesCollection.Clear(); chart.Title = this.Title; chart.XAxis.Label.Text = this.XTitle; chart.YAxis.Label.Text = this.YTitle; chart.TempDirectory = this.PhaysicalImagePath; chart.FileManager.FileName = this.FileName; chart.Width = this.PicWidth; chart.Height = this.PicHight; if (this.Type == MyChartType.Pie) { chart.Type = ChartType.Pie; chart.Use3D = true; chart.PieLabelMode = PieLabelMode.Outside; chart.DefaultSeries.DefaultElement.Transparency = 5; } else { chart.Type = ChartType.Combo; SeriesType st = (SeriesType)this.Type; chart.DefaultSeries.Type = st; //统一使用默认的序列图类型属性 chart.Use3D = this.Use3D; } //chart.Series.Type = this.Type;//生成对比的线型图时不适用 chart.Series.Name = this.SeriesName; chart.SeriesCollection.Add(this.DataSource); //chart.Series.Data = this.DataSource; chart.DefaultSeries.DefaultElement.ShowValue = true; chart.ShadingEffect = true; chart.Series.DefaultElement.ShowValue = true; } public SeriesCollection getArrayData(DataTable dt) { SeriesCollection SC = new SeriesCollection(); for (int i = 0; i < dt.Rows.Count; i++) { Series s = new Series(); s.Name = dt.Rows[i][0].ToString(); Element e = new Element(); // 每元素的名称 e.Name = dt.Rows[i][0].ToString(); // 每元素的大小数值 e.YValue = Convert.ToInt32(dt.Rows[i][1].ToString()); s.Elements.Add(e); SC.Add(s); } return SC; } public enum MyChartType { Marker = 1, Spline = 2, Line = 3, AreaLine = 4, Column = 5, Cylinder = 6, Bar = 7, Bubble = 8, AreaSpline = 9, Pyramid = 10, Cone = 11, BubbleShape = 12, BarSegmented = 13, Pie = 14 } }
创建图像
/// <summary> /// 主要功能实例化Charting类创建图像， /// 适合多维数据，依赖外部函数GetDataSource（DataTable dt）， /// 传入的数据列需要和GetDataSource（DataTable dt）函数中数据列相照应。 /// </summary> /// <param name="dt"></param> private void CreateImg(DataTable dt) { try { Charting c = new Charting(); if (ReportType.Value == "AreaReport") { c.DataSource = c.getArrayData(dt); } else { c.DataSource = GetDataSource(dt); } c.PicHight = 500; c.PicWidth = 800; c.Title = CreateTitle(); if (ReportType.Value == "AreaReport") { c.XTitle = "地区"; c.YTitle = "人数"; } else { c.XTitle = "日期"; c.YTitle = "人数"; } if (RadioButtonList1.SelectedValue == "1") { c.Type = Charting.MyChartType.Cylinder; } else { c.Type = Charting.MyChartType.Line; } if (ReportType.Value == "AreaReport") { c.Type = Charting.MyChartType.Pie; RadioButtonList1.Visible = false; } c.Use3D = false; //定义图像的存储路径 c.PhaysicalImagePath = "ChartImages"; c.SeriesName = "总计"; //图像的标题 c.FileName = CreateTitle(); //绘制chart1控件 c.CreateStatisticPic(this.Chart1); } catch (Exception ex) { } }
创建图像中的排序数据方法
private SeriesCollection GetDataSource(DataTable dt) { SeriesCollection sc = new SeriesCollection(); Series y = new Series(); Series y1 = new Series(); y.Name = "网络预约人数"; y1.Name = "网络到院人数"; string type = ReportType.Value; if (type == "HourDate") { y.Name = "网络对话预约人数"; y1.Name = "网络到院人数"; } #region 年龄统计中筛选年龄段 if (ReportType.Value == "AgeData") { int temp1 = 0; int temp2 = 0; for (int i = 0; i < dt.Rows.Count; i++) { Element e = new Element(); Element e1 = new Element(); if (Convert.ToInt32( dt.Rows[i]["date"])%5==0) { e.Name = dt.Rows[i]["date"].ToString(); e1.Name = dt.Rows[i]["date"].ToString(); if (!DBNull.Value.Equals(dt.Rows[i]["yuyuecount"])) { e.YValue = Convert.ToInt32(dt.Rows[i]["yuyuecount"]) + temp1; } else { e.YValue = 0; } if (!DBNull.Value.Equals(dt.Rows[i]["daoyuancount"])) { e1.YValue = Convert.ToInt32(dt.Rows[i]["daoyuancount"]) + temp2; } else { e1.YValue = 0; } y.Elements.Add(e); y1.Elements.Add(e1); temp1 = 0; temp2 = 0; } else { if (!DBNull.Value.Equals(dt.Rows[i]["yuyuecount"])) { temp1 += Convert.ToInt32(dt.Rows[i]["yuyuecount"]); } else { e.YValue = 0; } if (!DBNull.Value.Equals(dt.Rows[i]["daoyuancount"])) { temp2 += Convert.ToInt32(dt.Rows[i]["daoyuancount"]) ; } else { e1.YValue = 0; } } } } #endregion //普通统计 else { for (int i = 0; i < dt.Rows.Count; i++) { Element e = new Element(); Element e1 = new Element(); e.Name = dt.Rows[i]["date"].ToString(); e1.Name = dt.Rows[i]["date"].ToString(); if (!DBNull.Value.Equals(dt.Rows[i]["yuyuecount"])) { e.YValue = Convert.ToInt32(dt.Rows[i]["yuyuecount"]); } else { e.YValue = 0; } if (!DBNull.Value.Equals(dt.Rows[i]["daoyuancount"])) { e1.YValue = Convert.ToInt32(dt.Rows[i]["daoyuancount"]); } else { e1.YValue = 0; } y.Elements.Add(e); y1.Elements.Add(e1); } } sc.Add(y); sc.Add(y1); return sc; }
