这就是我到目前为止所做的。请仔细阅读整个描述以了解我的要求
System.Web.UI.DataVisualization.Charting.ChartArea chartArea1 = new System.Web.UI.DataVisualization.Charting.ChartArea();
System.Web.UI.DataVisualization.Charting.Legend legend1 = new System.Web.UI.DataVisualization.Charting.Legend();
System.Web.UI.DataVisualization.Charting.Series series1 = new System.Web.UI.DataVisualization.Charting.Series();
System.Web.UI.DataVisualization.Charting.Series series2 = new System.Web.UI.DataVisualization.Charting.Series();
System.Web.UI.DataVisualization.Charting.Chart chart1 = new System.Web.UI.DataVisualization.Charting.Chart();
//((System.ComponentModel.ISupportInitialize)(chart1)).BeginInit();
//this.SuspendLayout();
//
// chart1
//
chartArea1.Name = "ChartArea1";
chart1.ChartAreas.Add(chartArea1);
legend1.Name = "Legend1";
chart1.Legends.Add(legend1);
//chart1.Location = new System.Drawing.Point(49, 62);
//chart1.Name = "chart1";
series1.ChartArea = "ChartArea1";
series1.ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.StackedBar;
series1.Legend = "Legend1";
series1.Name = "Series2";
series2.ChartArea = "ChartArea1";
series2.ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.StackedBar;
series2.Legend = "Legend1";
series2.Name = "Series3";
chart1.Series.Add(series1);
chart1.Series.Add(series2);
//chart1.Size = new System.Drawing.Size(534, 300);
chart1.TabIndex = 0;
//chart1.Text = "chart1";
chart1.Series["Series2"].Points.Add(new DataPoint(1, 1));
chart1.Series["Series2"].Points.Add(new DataPoint(2, 4));
chart1.Series["Series2"].Points.Add(new DataPoint(3, 5));
chart1.Series["Series3"].Points.Add(new DataPoint(2, 3));
chart1.Series["Series2"].IsValueShownAsLabel = true;
chart1.Series["Series3"].IsValueShownAsLabel = true;
using (MemoryStream ms = new MemoryStream())
{
chart1.SaveImage(ms, ChartImageFormat.Png);
return File(ms.ToArray(), "image/png");
}
这将给出以下图表。
但我需要的是如下图，其中包含开始值和结束值
我如何得到它？
更新：我希望显示的数据存储在一个列表中，如下所示
List<dummyGraph> objGraphList = new List<dummyGraph>();
dummyGraph objDummyGraph = new dummyGraph();
objDummyGraph.RiskCategories = "Compliance,Law,Legislation";
objDummyGraph.HighImpactRisks = "4";
objDummyGraph.MediumImpactRisks = "1";
objDummyGraph.LowImpactRisks = "0";
objDummyGraph.NoImpactRisks = "5";
objDummyGraph.index = 1;
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.RiskCategories = "Construction";
objDummyGraph.HighImpactRisks = "5";
objDummyGraph.MediumImpactRisks = "1";
objDummyGraph.LowImpactRisks = "4";
objDummyGraph.NoImpactRisks = "0";
objDummyGraph.index = 2;
objGraphList.Add(objDummyGraph);
