Create graph using data from mutiple sheets

After searching this forum, I think there have already been a few similar posts, but I wasn't entirely sure that they are the same problem as I have.

I have a workbook with three sheets, each of which has matched data. I want to create a bar graph for each of the five rows from the three sheets (i.e. with six columns per graph (two from each sheet)).

I've attached a workbook and an image of how I would like the graph to look. Ideally, I want the x axis values to be the sheet names.

Many thanks

Righto - thanks for looking at it. Great forum!
