Question

我有100％堆积条形图。学生根据他们的出勤情况进行绑定，报告只是跟踪乐队人口的变化占学生总人数的百分比。在报表生成器中，这完全正常（除了它突出了我们的垃圾出席当然......）

问题出现在：

报表从报表生成器导出为PDF / Word / Excel /无论
报告已部署到SSRS服务器并通过浏览器
您将切换到报告的后续页面，然后返回到包含图表的页面。

在所有情况下，尽管实际图表保持不变，但Legend稍微失去了理智，并将前三项显示为100％：

我想不出有任何理由会发生这种情况......由于基础数据结构（令人遗憾的是基于报告模型，这意味着我无法调整报告），报告特别挑剔使用SQL）我最终必须使用自定义vb代码才能让它做我想做的事情，但我不明白为什么其中任何一个应该在服务器上或导出时改变它的行为。

所以我的问题是;为什么会发生这种情况，我该如何阻止它发生呢？

编辑：按要求：

数据集固有地以下面的格式返回数据。每个“周开始日期”每个学员ID都有一行。

我正在使用的自定义代码粘贴在下面（我不知道 - 不笑！）：

Private attendance_table As New System.Collections.Hashtable()
Private last_added_table As New System.Collections.Hashtable()

Public Function band_calc(ByVal attendance As Double) As String
    REM Define the bands that I want to track
    If attendance = 1 Then
        Return "A"
    ElseIf attendance >= 0.975 Then
        Return "B"
    ElseIf attendance >= 0.95 Then
        Return "C"
    ElseIf attendance >=  0.925 Then
        Return "D"
    ElseIf attendance >= 0.90 Then
        Return "E"
    ElseIf attendance >= 0.85 Then
        Return "F"
    ElseIf attendance >= 0.8 Then
        Return "G"
    Else
        Return "X"
    End If

End Function

Public Function get_attendance_band(ByVal week_start_date as String, ByVal learnerID As Integer, ByVal possibles As Integer, ByVal presents As Integer) As String


    If attendance_table Is Nothing Then 
        Dim attendance_table As New System.Collections.Hashtable()
    End If

    If last_added_table Is Nothing Then
        Dim last_added_table As New System.Collections.Hashtable()
    End If

    REM check if attendance_table has the Learner already
    If attendance_table.ContainsKey(learnerID) Then
        REM check if we've already added this week's data in
        If attendance_table(learnerID).ContainsKey(week_start_date) Then
            REM just return the band_calc for those data
            Return band_calc(attendance_table(learnerID)(week_start_date)(1) / attendance_table(learnerID)(week_start_date)(0))
        Else
            REM Add in this week to the hashtable. Add this weeks data to the last weeks data
            attendance_table(learnerID).Add(week_start_date, New Object() { possibles + attendance_table(learnerID)(last_added_table(learnerID))(0), presents + attendance_table(learnerID)(last_added_table(learnerID))(1)})

            REM record that this is now the last date updated for this learner
            last_added_table(learnerID) = week_start_date

            REM show the band!
            Return band_calc(attendance_table(learnerID)(week_start_date)(1) / attendance_table(learnerID)(week_start_date)(0))

        End If

    Else    
        attendance_table.Add(learnerID, New System.Collections.Hashtable())
        attendance_table(learnerID).Add(week_start_date, New Object() {possibles, presents})
        last_added_table.Add(learnerID, week_start_date)

        Return band_calc(attendance_table(learnerID)(week_start_date)(1) / attendance_table(learnerID)(week_start_date)(0))

    End If

End Function
