Excel chart - create second axis

Question

I've created a script which makes an Excel object, takes some data, generates a chart and then exports the chart as a JPG. The thing is it's a CPU report with one series for Mhz and one for % - and using only one axis results in it ending in the thousands
and not being able to see the second series. Do you know how to specify a second axis on the right-hand side (left for Mhz right for %) which would only go up to 100? I don't even know how to do it in Excel, never mind PowerShell.
Thanks in advance. Oh yeah, here's my code:
# Generate graph
$xRow = 1
$yRow = $rows
$objRange=$Worksheet.range("a${xRow}:c${yRow}")
$colCharts=$excel.Charts
$objChart=$colCharts.Add()
$objChart.ChartType=4
$objChart.Axes(0).CategoryType=2
$objChart.Axes(0).TickLabelSpacing=7
$objChart.HasTitle = $true
$objChart.ChartTitle.text = "CPU Report"
$a=$objChart.Activate
$savepath = "C:\"
$a=$objChart.export($savepath + "cpu.jpg","JPG")

Hi Bobbinspenguin,
If you want to add a second series in Excel chart with powershell, please refer to this article:

I hope this helps.
