Hello, for my excel class homework assignment I have to create couple charts, pies and map using the Power view and PowerPivot. I am trying to undo the changes that I made to the column chart and other charts I created under my PowerPivot sheet. Every time I make a change the undo button on my quick access tool bar is disabled, why? For example if I re-size the chart it won't let me undo it. On all the other sheets not using Power view I am able to undo any changes, but this only happens when I use the power view.
I am currently using Excel 2013.
