ASP.NET中使用C＃语言的动态饼图 [英] Dynamic pie chart in ASP.NET with C# language

问题描述

我想在饼图中运行时绑定数据，但我不知道x轴和y轴的值



什么我试过了：

  //   dstotal = objemp.getdata（）;  
  //   string s = dstotal.Tables [0] .Rows [0] [Mtotal]。ToString（）;  
  //   string s1 = dstotal.Tables [1] .Rows [0] [Etotal]。ToString（）;  
  //   int count = Convert.ToInt16（s）;  
  //   int count1 = Convert.ToInt16（s1）;  
  string  [] xVal = { 费用， 收入}; 
  double  [] yVal = { 3 ， 5 }; 
 Chart1.Series [ 0 ]。Points.DataBindXY（xVal，yVal）; 
 Chart1.Legends [ 0 ]。Enabled =  true ; 
 

解决方案

ASP.NET 4及以上版本有一个图表控件，可以使用饼图，但没有X ，Y轴你无法绑定饼图

见下面的片段我已经给出了一个样本来绑定饼图

  protected   void  Page_Load（ object  sender，EventArgs e） 
 {
  double  [] yValues = { 71 。 15 ， 23 。 19 ， 5 。 66 }; 
  string  [] xValues = {  AAA ，  BBB，  CCC}; 
 Chart1.Series [ 默认]。Points.DataBindXY（xValues，yValues）; 
 
 Chart1.Series [ 默认]。积分[ 0 ]。颜色= Color.MediumSeaGreen; 
 Chart1.Series [ 默认]。点[ 1 ]。颜色= Color.PaleGreen; 
 Chart1.Series [ 默认]。点[ 2 ]。颜色= Color.LawnGreen; 
 
 Chart1.Series [ 默认]。ChartType = SeriesChartType.Pie ; 
 
 Chart1.Series [ 默认] [  PieLabelStyle] =  禁用; 
 
 Chart1.ChartAreas [  ChartArea1]。Area3DStyle.Enable3D = < span class =code-keyword> true ; 
 
 Chart1.Legends [ 0 ]。Enabled =  true ; 
}

如何使用ASP.Net和C＃创建饼图 [ ^

i want to bind data at run time in a pie chart but i do not know the values of x-axis and y-axis

What I have tried:

//dstotal = objemp.getdata();
//string s = dstotal.Tables[0].Rows[0]["Mtotal"].ToString();
//string s1 = dstotal.Tables[1].Rows[0]["Etotal"].ToString();
//int count = Convert.ToInt16(s);
//int count1 = Convert.ToInt16(s1);
string[] xVal = { "Expenses", "Income" };
double[] yVal = { 3, 5 };
Chart1.Series[0].Points.DataBindXY(xVal, yVal);
Chart1.Legends[0].Enabled = true;

解决方案

ASP.NET 4 and above has a charting control, you can use pie chart from it, but without X,Y axis you are unable to bind pie chart
see below snippet in that i have given a sample to bind pie chart

protected void Page_Load(object sender, EventArgs e)
{
  double[] yValues = { 71.15, 23.19, 5.66 };
  string[] xValues = { "AAA", "BBB", "CCC" };
  Chart1.Series["Default"].Points.DataBindXY(xValues, yValues);
 
  Chart1.Series["Default"].Points[0].Color = Color.MediumSeaGreen;
  Chart1.Series["Default"].Points[1].Color = Color.PaleGreen;
  Chart1.Series["Default"].Points[2].Color = Color.LawnGreen;
 
  Chart1.Series["Default"].ChartType = SeriesChartType.Pie;
 
  Chart1.Series["Default"]["PieLabelStyle"] = "Disabled";
 
  Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;
 
  Chart1.Legends[0].Enabled = true;
}
