In earlier versions you could adjust the formatting of the chart, but it required a lot of clicks. Now when a chart is selected the DESIGN tab has a host of formatting tools!

One option is the ability to adjust the entire layout and visible elements with two clicks – 1. Choose layout options, 2. Choose layout:

I was able to adjust the layout and visible elements of the sample chart to each of these layouts with 1 click!
