Question

Hello I have written a code for generating the graph and it is working correctly.
The problem is it is taking lot of time to generate. and i am not getting why it is taking time.
the code is

    Dim cc As Chart

    Set cc = ActiveWorkbook.Charts.Add
    Set cc = cc.Location(Where:=xlLocationAsObject, name:=assume)

    With cc

     .ChartType = xlXYScatterLines

     With .Parent

       .Top = Columns(b).Offset(0, 4).Top
       .Left = Columns(b).Offset(0, 4).Left
       .name = "cc"

     End With

  End With

  Dim sc As Series
  Set sc = cc.SeriesCollection(1)

  With sc
      .Values = Columns(b).Offset(0, -3)
      .XValues = Columns(b).Offset(0, -5)
  End With

Please somebody help me

Try this, to just chart the rows of the column with actual data.

Sub makeChart(b As String, assume As String) 'i presupposed these arguments based on your code

Application.ScreenUpdating = False

Dim cc As Chart

Set cc = ActiveWorkbook.Charts.Add
Set cc = cc.Location(Where:=xlLocationAsObject, Name:=assume)

With cc

    .ChartType = xlXYScatterLines

    With .Parent

        .Top = Columns(b).Offset(0, 4).Top
        .Left = Columns(b).Offset(0, 4).Left
        .Name = "cc"

    End With

End With


Dim strValue As String, strXValue As String

'here you are using the passed column letter to find the specific column you want to chart
strValue = Split(Range(b & "1").Offset(, -3).Address, "$")(1) 'will return "C" if given column F
strXValue = Split(Range(b & "1").Offset(, -5).Address, "$")(1) 'will return "A" if given column F

Dim sc As Series
Set sc = cc.SeriesCollection(1)

With sc

    'will select from row 1 to the last true used row in the given column
    .Values = Range(strValue & "1:" & strValue & Range(strValue & Rows.Count).End(xlUp).Row)
    .XValues = Range(strXValue & "1:" & strXValue & Range(strXValue & Rows.Count).End(xlUp).Row)

End With

Application.ScreenUpdating = True

End Sub
