Hi Assuming you have a data set like that below

Labour Costs
500 100
600 200
700 300
800 400

Hiighlight everything including labels and create a simple line chart.
Then double-click on the line for one of the data series and a format
dialogure box appears....click the axis box...and select 2nd axis.
