Need help with chart for sales & labour

[cmacnab]

Hi all, I'm trying to do a chart with sales and labour costs. I would like to have a column chart for daily sales and have the labour cost as a point on that column for the day. I.e. if sales are $10k, that would be the first data point and labour at $5k would be a point half-way in that sales column. I have sales $$, labour $$ and also labour %. How can I show this correctly on the chart?

Thanks in advance.
