统计质量控制图VB代码中的错误

Question

我找到了一个宏在线，它创建了一个在线统计质量控制图表。因此，我有一个.Csv文件，看起来像一个excel工作表。我使用宏，所以我必须选择数据点。然后，我必须选择标签，然后它被绘制。

我的问题是，UL2 =(上限，2*标准差)和LL2=(下限，2*标准差)的错误条根本没有出现。所有其他错误条都会出现。如平均值，UL(上限)，LL(下限)，UL3和LL3，而不是UL2和LL2。

而且，数据点不是沿着它们应该在的平均线上移动的，它们也被移动。

我使用的一个示例表显示了它们，但这是在一个普通的excel文件中。之所以将它作为.CSV文件，是因为我使用另一个宏提取原始数据，并将其粘贴到一个新的.csv文件中。我想这就是原因，但我不能百分之百肯定。我在想你们能不能帮我。我对VBA相当陌生，所以请容忍我。

谢谢!

下面是创建控制图的代码：

这就是我画它的样子。UL2和LL2的错误条甚至不在那里。

Answer 1

因此，LCL1和LCL2在舍入后似乎是相同的值(以及UCL2 1/UCL2 2)。上面的加法函数只有小数点后两位。要查看它们之间的差异，请将舍入从小数点2位更改为3或4位。建议将平均值更改为3/4小数位以匹配，但更新的代码如下所示。

ActiveWorkbook.Names.Add Name:=Application.WorksheetFunction.Substitute(myChtObj.Name, " ", "") & "_LCL1", RefersToR1C1:="=" & avg_str & "- roundup(1*stdev(" & data_str & "),3)"
    ActiveWorkbook.Names.Add Name:=Application.WorksheetFunction.Substitute(myChtObj.Name, " ", "") & "_LCL2", RefersToR1C1:="=" & avg_str & "- roundup(2*stdev(" & data_str & "),3)"

    ActiveWorkbook.Names.Add Name:=Application.WorksheetFunction.Substitute(myChtObj.Name, " ", "") & "_UCL1", RefersToR1C1:="=" & avg_str & "+ roundup(1*stdev(" & data_str & "),3)"
