使用C#和SQL Server数据库在WinForms中的图表中添加第二个系列/条形图

我想使用C#和SQL Server在同一图表中添加另一个关于“未决案件”名称的系列。我想在同一张图表上显示“处置案件”和“未决案件”的条形图。我已经为cmd中的处置案例编写了查询。但我很困惑在同一天添加图表中的第二个条形图。这意味着我将有未决案件和已处理案件

方法与SQL查询一起显示在下面

public void ChartReportAllDaily()
{
       DataSet ds = new DataSet();

        try
        {
            conn.Open();

            SqlCommand cmd = new SqlCommand("SELECT NextDate, COUNT(CaseNo) AS DailyDisposal FROM dbo.Main_Cause_List WHERE (DisposalState = 'Disposed-of') GROUP BY NextDate", conn);

            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = cmd;
            da.Fill(ds, "Main_Cause_List");

            chart1.DataSource = ds.Tables["Main_Cause_List"];

            chart1.Series["Series1"].XValueMember = "NextDate";
            chart1.Series["Series1"].YValueMembers = "DailyDisposal";

            // To show chart value  
            chart1.Series["Series1"].IsValueShownAsLabel = true;
           
            chart1.ChartAreas[0].AxisX.Interval = 1;

            chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.LineWidth = 0;
            chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.LineWidth = 0;
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
        finally
        {
            conn.Close();
            conn.Dispose();
        }
    }

图表类型是条形图还是柱形图？到目前为止，它看起来像什么？它应该如何照顾？

NextDate

是日期还是日期时间？还是一个数字？还是一根绳子？？是否已经添加了第二个系列？是的，先生，类型为条形…我想按日期对它们进行分组。如果这些日期是对应的（即没有tme分数），则第二个系列将显示除第一个系列之外的条形。你试过了吗？你有选择的工作吗？我只需要日期不需要时间先生…我不是问你需要什么，而是问你实际拥有什么。这应该是一个答案吗？如果没有，请编辑问题。如果是，请解释！顺便说一句：上面的图表显示的不是条而是列！对不起，我错了…印刷错误先生，，，谢谢你的澄清…@TaW
