Reverse Order of Y Axis...keep x axis the same

So I am trying to chart a series of revenue data. Currently, when I select the data and make it into a bar graph, it plots the data from smallest to largest on the y-axis. Instead, I want it to plot the data from largest to smallest on the y-axis.

When I click on "Categories in reverse order" it flips the y axis revenue figures...but also then sticks the x-axis at the top instead of leaving it at the bottom...how do I make it stay at the bottom? Is this possible in Excel 2013?

Thanks,
Dom
