How can I display a Bar chart without it being stacked?

[#1]

I have 2 dimensions in my chart, is it possible to display them in a standard bar chart format, not stacked.

For instance I have percentage sales against month sold and i want to know how many sales for each make car displayed against each other.

It allows them to be stacked which would give over 100% total which doesnt look right. As there are only a few makes of cars I would prefer it t display side by side.

The grouped and stacked option in the style tab is greyed out and cant be changed.

Has anyone got any ideas??? i cant seem to workout how to do it.

Thanks

You are probably using more than 1 expression, right?

I am using one expression but 2 dimensions.
