是否可以匹配c＃winforms中两个不同数据集的图表中的两个系列数据

Question

我正在开发一个应用程序来检查已检查的图表并根据工单号编制缺陷。在查看图表并比较实际数据后，我意识到该系列与工单号不匹配。我不知道如何将两个系列与工单号相匹配以获得正确的图表。

这是我的数据拉动Boards_Inspected拉出的代码

public DataSet Get_Boards_Inspected(string startDate, string endDate, int location)
    {
        DataSet ds = new DataSet();

        NpgsqlConnection conn = DatabaseConnection.getConnectionString();
        try
        {
            conn.Open();
            NpgsqlDataAdapter da = new NpgsqlDataAdapter("select new_table.top_or_bottom, new_table.board_wo_number, count(new_table.board_serial_number) from" +
            " (select distinct master_board.board_serial_number, board_wo.board_wo_number,board_wo.board_part_number, board_time.top_or_bottom from master_board" +
            " inner join board_time on board_time.board_time_id = master_board.id" +
            " inner join board_wo on board_wo.board_wo_number = master_board.board_wo_number" +
            " where time_in between '" + startDate + "' and '" + endDate + "'" +
            " and board_time.location_id = '" + location + "')" +
            " as new_table" +
            " group by new_table.top_or_bottom, new_table.board_wo_number" +
            " order by top_or_bottom;", conn);
            ds.Reset();
            da.Fill(ds);
            da.Dispose();
        }
        catch (Exception ex)
        {
            MessageBox.Show("An unexpected error has occured with the application. \n" +
            "An email has been sent to the software developer for analysis. \n" +
            "this program will now close.", "Unexpected Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

            eMessageBody = ex.ToString();
            Mail sendMessage = new Mail();
            sendMessage.SendSMTP(eMessageBody, eMessageSubject);
            Application.Exit();
        }
        finally
        {
            conn.Close();
        }
        return ds;
    }

Both data sets, trying to line them up in a chart

Answer 1

使用图表控件时，这是一个经典错误。

他们似乎自动完成所有事情，直到你更接近并解决问题。

以下是规则：

所有值，X值和所有Y值都在内部存储为双精度。

如果你输入数字，一切正常。如果您输入任何其他数据类型，那么您将在某个地方遇到麻烦。

起初，一切似乎都有效，你输入的东西在标签中很好地显示出来。

但是当你想使用Chart的任何高级能力时，很有可能它起作用..

这可以像格式化标签一样简单，仅适用于字符串格式。如果你想使用数字格式，你需要输入数字！

您正在解决不同系列中匹配上升点的问题。

您已将X值作为字符串输入，因此只要数据点需要匹配超出添加顺序，就会出现问题。

你可以按照精确的顺序喂它们，但你需要了解会发生什么......

让我们看看幕后......：如果您使用调试器来查看系列数据点的x值，您会惊讶地发现它们都是0！您输入的字符串已进入标签，但X值是转换为双精度失败的结果，导致0。这意味着所有数据点都具有相同的X值！

您有两种选择：

• 将它们全部同步添加，所有系列中的点数相同且点数相同。

• 为X值使用数字。

您的workOrder 看起来像一个数字;如果它是你可以使用它，如果你想，但它会根据这些数字分散数据。可能不是一个好主意。相反，您可以为每个工作订单分配一个索引，然后使用它。

要创建漂亮的标签，请为每个数据点使用AxisLabel属性！

最简单的方法是首先用值和轴标签创建DataPoint，然后使用工具提示和颜色等等，然后将其添加到点集合中。

现在让我们沉入其中，看看这张图表：

这是创建它的代码：

private void Form1_Load(object sender, EventArgs e)
{
    Random R = new Random(1);
    List<Tuple<Series, int>> misses = new List<Tuple<Series, int>>();
    chart1.Series.Clear();

    for (int i = 0; i < 3; i++ )
    {
        Series s = new Series("S" + (i + 1));
        s.ChartType = SeriesChartType.Column;
        chart1.Series.Add(s);
    }

    chart1.ChartAreas[0].AxisX.Interval = 1;

    foreach(Series s in chart1.Series)
    {
        for (int i = 0; i < 30; i+=3)
        {
            if (R.Next(3) > 0) s.Points.AddXY(i, i+1);
            else misses.Add(new Tuple<Series, int>(s, i));
        }
    }

    foreach (Tuple<Series, int> m in misses)
    {
        if (m.Item1.Name == "S1") m.Item1.Points.AddXY(m.Item2 + "X", m.Item2 + 5);
        else m.Item1.Points.AddXY(m.Item2, m.Item2 + 5);
    }

    for (int i = 0; i < chart1.Series[0].Points.Count - 1; i++)
    {
        chart1.Series[0].Points[i].AxisLabel = chart1.Series[0].Points[i].XValue + "%";
    }
}

让我们来看看发生的事情：

我先创建三个系列，然后填入几个点。但是我随机地将几个插槽留空。

我将这些存储在元组列表中，以便稍后我可以将它们无序添加。

你可以看到他们都匹配，蓝色系列'S1'除外。

你能明白为什么吗？

我总是使用一个很好的数字作为X值，但不是蓝调系列中的遗漏点，我在数字上附加了一个“X”。

现在这些点也被添加，但是所有的X值都是0，所以它们都位于0位置。

注意：请注意，以上 代码可以使用。是学习的代码，以了解Chart值的数据类型以及将字符串添加为X值的后果！

Answer 2

我想通了，我首先将我的DataSet改为DataTables。然后我在DataTable 1中创建了一个新列，它将在DataTable 2中保存计数字段。然后循环遍历DataTable 1中的所有行并循环访问DataTable 2并放置一个select条件以匹配top_or_bottom和board_wo_fields并拉出计数值对于DataTable 2中的每个匹配，并将它们放在DataTable 1中。

DataTable dt1 = DA.Get_Boards_Inspected(startDate, endDate, location);
                DataTable dt2 = DA2.Get_Boards_With_Issue(startDate, endDate, location);


                DataColumn newCol = new DataColumn("dcount", typeof(System.Object));
                newCol.AllowDBNull = true;
                dt1.Columns.Add(newCol);
                foreach(DataRow r in dt1.Rows)
                {
                    object wo = (r["board_wo_number"]).ToString();
                    object tp = (r["top_or_bottom"]).ToString();

                    if (tp == "")
                    {
                        foreach (DataRow r1 in dt2.Select("board_wo_number = '" + wo + "'"))
                        {
                            if (r1["count"] == DBNull.Value)
                                r["dcount"] = 0;
                            else
                                r["dcount"] = (r1["count"]);

                    }
                    else
                    {
                        foreach (DataRow r1 in dt2.Select("board_wo_number = '" + wo + "' and top_or_bottom = '" + tp + "'"))
                        {
                            if (r1["count"] == DBNull.Value)
                                r["dcount"] = 0;
                            else
                                r["dcount"] = (r1["count"]);
                        }
                    }
                }

                foreach (DataRow dr in dt1.Rows)
                {
                    object tpn = (dr["top_or_bottom"]);
