View chart full screen in Excel 2013?

Hello

How do I view an Excel 2013 chart full screen ie. no toolbars or ribbons....just the chart at full/max size. I ultimately want to take the highest resolution screenshot of it and import it in to a graphics program.
If I could achieve the same thing by printing it to a large page format PDF document (that can be imported in to the graphics program) at high resolution please let me know if that would essentially give me the same thing, even possibly allowing me to save it as an image at a higher resolution than that of my monitor.
