Question

您好我想打表在我的C＃aplication（WinForm的） 我的目标很简单，我想在图表显示有多少人选择A答案，B答案等 类似的东西在这

聊天使用35值 'Y'，我想让它DINAMIC基于一共有多少答案（答案A +答案B = 15 + 20）

我已经尝试这样的事情 //（方法A）

this.myChart.Series["Answer"].Points.AddY("Answer A"); 
this.myChart.Series["Answer"].Points.AddY("Answer A"); 
this.myChart.Series["Answer"].Points.AddY("Answer B"); 

//AND (method B) 
this.myChart.Series["Answer"].Points.AddXY("Answer A", 1); 
this.myChart.Series["Answer"].Points.AddXY("Answer B", 1); 
this.myChart.Series["Answer"].Points.AddXY("Answer B", 2); 
this.myChart.Series["Answer"].Points.AddXY("Answer B", 3); 
this.myChart.Series["Answer"].Points.AddXY("Answer B", 4); 
this.myChart.Series["Answer"].Points.AddXY("Answer A", 2); 

//导致方法B

但它的结果并不像我想
anyidea怎么办呢？

Answer 1

int sumOfAnswerA = // get the sum of ppl choose A from your data 
int sumOfAnswerB = // get the sum of ppl choose B from your data. 

现在你可以在你的图表

this.myChart.Series["Answer"].Points.AddXY("Answer A", sumOfAnswerA); 
this.myChart.Series["Answer"].Points.AddXY("Answer B", sumOfAnswerB);
