根據更改輸入值的更新數據創建Excel圖形

Question

這是事情：我確實有能源模型。結果是牆壁，地板，窗戶，通風，屋頂的能量損失的數據（瓦特）。我模型中的變化部分是外部溫度。我編寫了一個宏，將溫度從-10攝氏度改爲10攝氏度。在正常的餅圖中，這很好地工作。因此，溫度場會發生變化，牆壁，地板等的值會在各自的領域更新。我想要一個圖形（線條或散點圖），顯示所有5個（牆壁，地板等）的溫度（x軸）和功率（瓦特，y軸）我失去了能量。

如何做到這一點？我可以（我必須）收集數據，然後在最後呈現在圖表中嗎？或者，當溫度變化時，我可以告訴excel擴展每個新值的圖表嗎？此時，我只能在或多或少的字段中顯示實際的數據。

我希望你能理解我的問題，並且有人能指引我走向正確的方向。

這是我想出了到目前爲止的代碼：由宏改變了 「Temperaturen」

橙色部分：

Sub BtnBuitenTemp() 
Dim PauseTime, Start 

Dim ws1 As Worksheet 
Set ws1 = Sheets(1) 

Dim ws2 As Worksheet 
Set ws2 = Sheets(2) 

Dim cell As Range 

' loop through temperature values given on Sheet(2) 
' for now these range from -10 to 10 
For Each cell In ws2.Range("A20:A40") 

    ' update values in temperature cell 
    ws1.Cells.Range("D10").Value = cell.Value 

    ' add some pause 
    PauseTime = 1 
    Start = Timer 

    Do While Timer < Start + PauseTime 
     DoEvents 
    Loop 
Next 

End Sub 

和截圖。因此所有其他數據將被更新並顯示在圖表中。該圖表只會更新此時的y軸值。我想循環溫度範圍（並在x軸上顯示），並將圖表中的先前值保持在各自的溫度。 （我也不能夠顯示x軸的範圍。）

（更新）

好的，我做現在有一個XY散點圖圖形和我可以設置在x軸上。這是我做到目前爲止有：

Sub BtnBuitenTemp() 

Dim PauseTime, Start 

Dim tbu_min As Integer 
Dim tbu_max As Integer 

Dim ws1 As Worksheet 
Set ws1 = Sheets(1) 

' get user values for min and max temp 
tbu_min = ws1.Range("TempBuitenMin").Value 
tbu_max = ws1.Range("TempBuitenMax").Value 

' set chart x axis values to user input 
With ws1.ChartObjects("Chart 7").Chart 
    With .Axes(xlCategory) 
     .MinimumScale = tbu_min 
     .MaximumScale = tbu_max 
    End With 
End With 

For temp = tbu_min To tbu_max 
    ' update values in temperature cell 
    ws1.Cells.Range("D10").Value = temp 

    ' add some pause 
    PauseTime = 0.5 
    Start = Timer 

    Do While Timer < Start + PauseTime 
     DoEvents 
    Loop 
Next temp 

End Sub 

而且，看起來像：

現在我只需要更新在合適的溫度數據...

• 更新2 -

我更新了我的xy數據散點圖。我忘了插入「系列X值」。現在右邊顯示的溫度是正確的。我現在只需要保持輸出的視野;此時它每次都刷新圖形。

嗯，我確實解決了我的問題。不是我想要的方式，但我沒有時間去尋找另一種方式。我現在收集所有數據並從我的宏中繪製圖表。這是一個訣竅。

Sub BtnBuitenTemp() 

Dim PauseTime, Start

Dim addTotal As Boolean 

' get user values for min and max temp 
tbu_min = ws1.Range("TempBuitenMin").Value 
tbu_max = ws1.Range("TempBuitenMax").Value 

' how many datapoints are there 
Dim xPoints() As Integer 

' add surfaces 
Dim muur() As Integer 
Dim vloer() As Integer

ReDim xPoints(dataSize) 

ReDim muur(dataSize)

ReDim ventilatie(dataSize) 
ReDim totaal(dataSize) 



' collect data 
dataCounter = 0 
For temp = tbu_min To tbu_max 

    ' update values in temperature cell 
    ws1.Cells.Range("D10").Value = temp 
    ' add x for series 
    xPoints(dataCounter) = temp 

    ' add data for y series 
    muur(dataCounter) = ws1.Cells.Range("O24").Value

    ventilatie(dataCounter) = ws1.Cells.Range("O68").Value 
    totaal(dataCounter) = ws1.Cells.Range("O74").Value 

    ' next 
    dataCounter = dataCounter + 1
