Excel Graphs and VB

I have a program that creates an Excel spreadsheet and creates a line graph on the spreadsheet. It works great except I need to add another line to the graph. How do I do that? Here is the code I use to create everything:

VB Code:

Dim objExcel As Excel.Application
Dim objWorkBook As Excel.Workbook
Dim objWorkSheet As Excel.Worksheet
Dim objXLRange As Excel.Range
Dim objXLChart As Excel.Chart
 
Set objExcel = CreateObject("Excel.Application")
Set objWorkBook = objExcel.Workbooks.Add
Set objWorkSheet = objWorkBook.Worksheets(1)
 
Set objXLRange = objWorkSheet.Range("E2", RangeX)
Set objXLChart = objWorkSheet.Application.Charts.Add
With objXLChart
    .ChartType = xlLine
    .SetSourceData objXLRange, xlColumns
End With

This is not all the code understand, just enough to let you know how I am doing it all.

Just use the macro-recorder and look what code that generates, copy-adjust-past.

Because I'm no Excel expert and have no idea of how to do that.

It is quite easy, start the excel macro-recorder (Alt-F8).
Do what you want to do (add the line to the chart) just how you do it normally.
Stop the macro-recorder (it has a stop-button like a cd-player)
Look into the code.

I don't know why this thread got moved to VBA because I'm not using VBA. I am using VB to do this. Anyway, this is the code I used:

VB Code:

'add another series from your sheet called MySheet
With objXLChart
    .ChartArea.Select
    i = .SeriesCollection.Count + 1
    .SeriesCollection.NewSeries
    .SeriesCollection(i).Name = "=Sheet1!R2C6"
    .SeriesCollection(i).XValues = "=Sheet1!R2C6:" & RangeY & "C6"
    .SeriesCollection(i).Values = "=Sheet1!R2C6:" & RangeY & "C6"
End With

You may be using VB, but the language used to work in Excel is VBA ;)
