如何逐行显示？ [英] How to display chart by row value?

问题描述

test1 | test2 | test3 | test4 |

125 | 143 | 144 | 123

123 | 123 | 154 | 134



这是一张表，通常用于显示我们采用列值的图表，第一列是x轴，第二列是y轴...



现在我的问题是我需要根据上面的表格显示它...是否有任何代码我可以按行而不是列来显示我的表格在图表上方???

如何将我的表格显示在图表上？

显示如何根据数据绑定X和Y访问。



希望这有帮助



根据评论添加示例代码段

  string  [] x =  new  串 [dt.Columns.Count]; 
  string  [] y =  new   string [dt.Columns.Count]; 
  for （ int  i =  0 ; i <  dt.Columns.Count; i ++）
 {
  if （i ==  0 ）
 {
  //  获取行值并分配给stringarray如果需要整数转换为整数 
x = Array.ConvertAll（dt.Rows [i] .ItemArray，item => item.ToString （））; 
 
} 
  else   if （i ==  1 ）
 {
y = Array.ConvertAll（dt.Rows [i] .ItemArray，item = >  item.ToString（））; 
} 
 
 
} 

注意：

无效检查未完成的项目，你应该照顾那些

现在使用这个尝试绑定X和Y轴

http://blogs.msdn.com/b/alexgor/archive/2009/02/21/data-binding-ms-chart-control.aspx[^]

Shows how to bind the X and Y access according to the Data.

Hope this helps

Adding a sample code snippet as per the comment

string[] x = new string[dt.Columns.Count];
            string[] y = new string[dt.Columns.Count];
            for (int i = 0; i < dt.Columns.Count; i++)
            {
                if (i == 0)
                {
                    //fetching the row values and assigning to stringarray if need integers convert to integers
                    x  = Array.ConvertAll( dt.Rows[i].ItemArray,item=>item.ToString());

                }
                else if (i==1)
                {
                    y = Array.ConvertAll(dt.Rows[i].ItemArray, item => item.ToString());
                }


            }

Note:
Null checks for the items not done, you should take care of those
Now using this try to bind the X and Y axis
