通过使用以下代码,我的图表看起来像代码之后的图像。
我的问题是现在条形和y轴点未正确对齐。
如何在同一行显示范围栏及其对应的y轴值?
List<dummyGraph> objGraphList = new List<dummyGraph>();
dummyGraph objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Underwriter";
objDummyGraph.min = 1;
objDummyGraph.max = 8;
objDummyGraph.Median = 1;
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Construction";
objDummyGraph.min = 2;
objDummyGraph.max = 5;
objDummyGraph.Median = 2;
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Design";
objDummyGraph.min = 3;
objDummyGraph.max = 6;
objDummyGraph.Median = 3;
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Partner";
objDummyGraph.min = 4;
objDummyGraph.max = 6;
objDummyGraph.Median = 3;
objGraphList.Add(objDummyGraph);
System.Web.UI.DataVisualization.Charting.Chart chart1 = new System.Web.UI.DataVisualization.Charting.Chart();
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 seriesInstance;
List<System.Web.UI.DataVisualization.Charting.Series> seriesList = new List<System.Web.UI.DataVisualization.Charting.Series>();
int xordinal = 0;
foreach (var i in objGraphList)
{
seriesInstance = new System.Web.UI.DataVisualization.Charting.Series(i.TKFEType);
seriesInstance.ChartType = SeriesChartType.RangeBar;
seriesInstance.Color = Color.SkyBlue;
seriesInstance.YValuesPerPoint = 2;
seriesInstance.AxisLabel = i.TKFEType;
double yplot1 = (double)i.min;
double yplot2 = (double)i.max;
seriesInstance.IsValueShownAsLabel = true;
xordinal = xordinal + 1;
seriesInstance.Points.AddXY(xordinal, yplot1, yplot2);
chart1.Series.Add(seriesInstance);
}
chart1.ChartAreas.Add(chartArea1);
chart1.ChartAreas[0].AxisY.Interval = 1;
chartArea1 = chart1.ChartAreas[0];
chartArea1.AxisY.IsStartedFromZero = true;
chartArea1.AxisY.Enabled = AxisEnabled.False;
chartArea1.AlignmentOrientation = AreaAlignmentOrientations.All;
using (MemoryStream ms = new MemoryStream())
{
chart1.SaveImage(ms, ChartImageFormat.Png);
return File(ms.ToArray(), "image/png");
}
样条图疑问
我有一个样条图。我需要显示从x(例如:Underwriter)到y(例如:200)的直线,如下图所示。我该怎么做?
更新后的代码:
public ActionResult MMBRChart()
{
//Area for generating line chart
List<dummyGraph> objGraphList = new List<dummyGraph>();
dummyGraph objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Underwriter";
objDummyGraph.min = 1;
objDummyGraph.max = 8;
objDummyGraph.Median = "201";
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Construction";
objDummyGraph.min = 2;
objDummyGraph.max = 5;
objDummyGraph.Median = "187";
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Design";
objDummyGraph.min = 3;
objDummyGraph.max = 6;
objDummyGraph.Median = "243";
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Partner";
objDummyGraph.min = 4;
objDummyGraph.max = 6;
objDummyGraph.Median = "200";
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Auditor";
objDummyGraph.min = 4;
objDummyGraph.max = 6;
objDummyGraph.Median = "29";
objGraphList.Add(objDummyGraph);
objDummyGraph = new dummyGraph();
objDummyGraph.TKFEType = "Associate";
objDummyGraph.min = 4;
objDummyGraph.max = 6;
objDummyGraph.Median = "198";
objGraphList.Add(objDummyGraph);

System.Web.UI.DataVisualization.Charting.Series seriesInstance = new Series();
chart1.Titles.Add("Median MBR");//Add chart title
chart1.Series.Add(seriesInstance);
chart1.Series[0].Points.DataBindXY(objGraphList.Select(x => x.TKFEType).ToList(), objGraphList.Select(x => x.Median).ToList());

chart1.Series[0].MarkerColor = Color.Blue;
chart1.Series[0].Name = "MyGraph";
seriesInstance = new System.Web.UI.DataVisualization.Charting.Series("lineSeries");
//seriesInstance.ChartType = SeriesChartType.Bar;//Set chart type here
seriesInstance.Color = Color.SkyBlue;
seriesInstance.YValuesPerPoint = 2;
chart1.Series.Add(seriesInstance);
int j = 0;
foreach (var p in objGraphList)
{
//chart1.Series[1].Points.AddXY(j, p.max);
j = j + 1;
chart1.Series[1].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Bar;
chart1.Series[1].Points.AddXY(p.TKFEType, p.Median);

using (MemoryStream ms = new MemoryStream())

答案 0 :(得分:1)
您要在图表中添加多个系列。不确定那是你的意图。此外,您使用TKFEType
作为标签,而不是轴的实际值。这些因素加在一起可能会错误地调整您的图表。以下是我的建议:
List<DummyGraph> list1 = new List<DummyGraph>();
list1.Add(new DummyGraph { TKFEType = "Underwritter", Min = 1, Max = 8, Median = 1 });
list1.Add(new DummyGraph { TKFEType = "Construction", Min = 2, Max = 5, Median = 2 });
list1.Add(new DummyGraph { TKFEType = "Design", Min = 3, Max = 6, Median = 3 });
list1.Add(new DummyGraph { TKFEType = "Partner", Min = 4, Max = 6, Median = 4 });
Chart1.DataSource = list1;
Chart1.Series[0].XValueMember = "TKFEType";
Chart1.Series[0].YValueMembers = "Min, Max";
Chart1.DataBind();
