different unit in column values and line values

Dear All,

I want to show sales total and hit rate in the line and column chart.

I want to lock the unit of sales total in million and keep unit of hit rate in %.

So I set the unit in data labels, the sales total unit change to million, while the hit rate unit change to 0.00%M

how can I only change the unit of sales total and keep the hit rate in %?

Thanks
