Editing any slide object works the same way, irrespective of whether you are editing a picture, a chart, some SmartArt, or even text. You select the object you want to edit and change some attributes. You then get to see your changes, and then you either undo your changes if you are not too happy with them, or just accept them. You can then start working on another object! What if you could see/preview how an actual change will look on the slide object before you decide to accept or decline that change? PowerPoint Live Preview allows you to do just that.
