Scatter Plot graphing excel VBA - wont graph my range of data - vba

Question

Here's the section of the code that is giving me trouble. I incorporated messagebox's to let me know that things are working up to that given point. So when I type "MsgBox xaxis.Address()" it comes out like $C$20:$C$42. Which is what im looking to graph on the x-axis. The issue is, my graph doesnt actually show up with that on the x-axis... it graphs like the entire sheet. I am guessing my issue lies with the syntax of xaxis that I am using.
Dim StartTime As Range
Dim EndTime As Range
Set StartTime = wb1.Sheets("Sheet2").Range("C:C").Find(wb1.Sheets("Sheet1").Range("$B$2").Text, MatchCase:=False, lookat:=xlWhole)
Set EndTime = wb1.Sheets("Sheet2").Range("C:C").Find(wb1.Sheets("Sheet1").Range("B3").Text, MatchCase:=False, lookat:=xlWhole)
'If Not StartTime Is Nothing Then
'End If
MsgBox StartTime.Address()
MsgBox EndTime.Address()
MsgBox StartTime.Value
MsgBox EndTime.Value
MsgBox "Hi"
Dim xaxis As Range
Dim yaxis As Range
Set xaxis = Range(StartTime.Address & ":" & EndTime.Address)
MsgBox xaxis.Address
'Set xaxis = Range("$C$16", Range("$C$16").End(xlDown))
Set yaxis = xaxis.Offset(0, ColumnOffset:=1)
MsgBox yaxis.Address
'''''''''''''''''''''''
'Dim x As String
'Dim y As String
' x = xaxis.Address
'MsgBox "Hi"
'y = yaxis.Address
'MsgBox x
Set Chrt = Charts.Add
With Chrt
.ChartType = xlXYScatter
.SeriesCollection.NewSeries
'.SeriesCollection(1).Name = "=""Scatter Chart"""
.SeriesCollection(1).Values = yaxis
.SeriesCollection(1).XValues = xaxis
'Titles
.HasTitle = True
.ChartTitle.Characters.Text = "Platen1"
.Axes(xlCategory, xlPrimary).HasTitle = True
.Axes(xlCategory, xlPrimary).AxisTitle.Characters.Text = "Time (Seconds)"
.Axes(xlValue, xlPrimary).HasTitle = True
.Axes(xlValue, xlPrimary).AxisTitle.Characters.Text = "Temp (Deg. C)"
.Axes(xlCategory).HasMajorGridlines = True
'Formatting
.Axes(xlCategory).HasMinorGridlines = False
.Axes(xlValue).HasMajorGridlines = True
.Axes(xlValue).HasMinorGridlines = False
.HasLegend = False
End With
My overall goal: I have a spreadsheet with data that gets updated daily. I need the user to be able to input a start time, end time, and then machine number. This needs to be used to generate a graph from that data. The start and end time are always in column C, but the specific rows are always changing. So what I do is I locate the matching start time and end time from the data, and then I create this range (StartTime or EndTime). The machine will determine the column of data to use for the y-axis which im just offsetting from the x-axis.
Any help would be greatly appreciated.
Edit: I fixed the above by adding the following code right under the chart creation:
Do Until .SeriesCollection.Count = 0
.SeriesCollection(1).Delete
Loop
The issue i realize is that the "xaxis" and "yaxis" are grabbing data from Sheet1 while i want it to grab data from Sheet 2. How do I go about declaring that it should be graphing from Sheet2?

Answer 1

Do it like this
Set xaxis = Sheets("Sheet2").Range(StartTime.Address & ":" & EndTime.Address)
Set yaxis = xaxis.Offset(0, ColumnOffset:=1)
