mulit plot from different sheets in one chart with VBA - vba

Question

My problem is that I want to make many graph in one chart but the data is from different sheets.
At the moment my code can only take multi data from one sheet, meaning I can plot 2 graph from one sheet.
My code at the moment is:
Sub ChartSheet()
Dim ChartSheet1 As Chart
Set ChartSheet1 = Charts.Add
With ChartSheet1
.SetSourceData Source:=Sheets("Sheet1").Range("E12:E6232, Y12:Y6232")
.ChartType = xlLine
.HasTitle = True
.ChartTitle.Characters.Text = "Test Chart"
.Axes(xlCategory, xlPrimary).HasTitle = True
.Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text = "x"
.Axes(xlValue, xlPrimary).HasTitle = True
.Axes(xlValue, xlPrimary).AxisTitle.Characters.Text = "y"
End With
End Sub
What I want is to say:
.SetSourceData Source:=Sheets("Sheet1").Range("E12:E6232, Y12:Y6232")
.SetSourceData Source:=Sheets("Sheet2").Range("D12:E23")
.SetSourceData Source:=Sheets("Sheet3").Range("Y12:Y6232, G27:G496, H3:5977")
and so on..
But when I do this my code it only print the last line from .SetSoureData
Hope some of you can help me work around this, Many thank in advarnce :)
Update:
I found abit of a work around by looping but this is not my total answer
But here is my other code:
Sub MultiSheetPlot()
Dim cht As Chart, s As Series, xRng As Range
Dim i As Long, chartName As String
Set cht = Charts.Add
cht.ChartType = xlLine
For i = 1 To 3
chartName = "Sheet" & i
Set xRng = Sheets("Sheet1").Range("A1:A20, C1:C20")
With cht.SeriesCollection.NewSeries()
.Values = xRng
.Name = chartName
End With
Next i
End Sub
the problem in this code is that it ignores the last range I define like the C10:C20

Responding to your latest update, I have a Sub that creates a series each time it's called from MultiSheetPlot Sub.
You can actually add more parameters to this Sub (as long as you remeber to pass them in the Calling).
Option Explicit
Dim cht As Chart
Sub MultiSheetPlot()
Set cht = Charts.Add
cht.ChartType = xlLine
' call the series creation chart function (each time for each series you want to add to the existing chart
Call Create_SeriesChart("Sheet1", Sheets("Sheet1").Range("E12:E6232"), 1, True, msoThemeColorText1)
Call Create_SeriesChart("Sheet1", Sheets("Sheet1").Range("Y12:Y6232"), 1, True, msoThemeColorText1)
End Sub
' ------ this Sub creates a series to the chart, it receives the following parameters: ------
' 1. seriesName - String
' 2. serValues - Range
' 3. lineWeight - Double (the weight of the line)
' 4. lineVis - Boolean (if you want to hide a certail series)
' 5. lineColor - MsoColorType (using the current's PC Theme colors
Sub Create_SeriesChart(seriesName As String, serValues As Range, lineWeight As Double, lineVis As Boolean, lineColor As MsoColorType)
Dim Ser As Series
Set Ser = cht.SeriesCollection.NewSeries
With Ser
.Name = seriesName
.Values = serValues
.Format.Line.Weight = lineWeight
If lineVis = True Then
.Format.Line.Visible = msoTrue
Else
.Format.Line.Visible = msoFalse
End If
.Format.Line.ForeColor.ObjectThemeColor = lineColor ' Line color Black
End With
End Sub

My solution is use Name of plage, you can give a name of your range
Like in my photo :
Everytime when you want to use these datas you just need call them
Like this plage i gived them name Poste_EtatDeLaDemande
When i want to use these elements i just call it like Range("Poste_EtatDeLaDemande") Excel will find it you don't need tell them where it is anymore ; )
