Two axis- is it possible to have one bar and one point?

hi, i have created a BAR chart(horizontal) and have two series of data with two axis at top and bottom. I would like one of the data series not to be represented with a bar but with a point, like on a scatter graph. Is this possible, and if so, please could you let me know asap how to do this. Important bit of work being carried out. Thank you so much for your time.
