如何将饼图绑定到数据源 [英] how to bind a Pie Chart to a Datasource

问题描述

大家好，



我的目标是在饼图上显示我的数据库表值（我有两列，分别为Total和Used）。我使用WPFToolkit进行图表控件并创建了一个饼图结构。



但我仍然坚持将图表绑定到数据源。



任何人都可以建议我一个解决方案。谢谢！



这就是我的尝试：

Hello all,

My goal is to display my database table values ( I have two columns as Total and Used) on a pie chart. I used the WPFToolkit for the chart control and created a pie chart structure.

but I am stuck with binding the chart to the datasource.

Any one can pls suggest me a solution. Thanks !

This is what i have tried :

public List<ram> getRamData()
      {
          List<ram> list = new List<ram>();
          con.Open();
          string query = "select top 1 Used,Total from UsageRam";
          cmd = new SqlCommand(query, con);
          dr = cmd.ExecuteReader();
          while (dr.Read())
          {
              var reading = new ram
              {
                  Used = Convert.ToInt32(dr[0]),
                  Total = dr[1].ToString()
              };
              list.Add(reading);
          }
