How do you add two input ranges to a Histogram

Hi All,

I was wanting some guidance if possible. I am using excel 2010 and I would like to know how I enter two input ranges into a Histogram.

I have two months of daily data that I need to compare in a histogram for an assignment.

I can create and display one of the data sets but there is no input range for a second set.

Could some more knowledgeable person than I am please instruct me how to do this.

Thank you

Daniel
