Powerpoint BarGraph Problem

[edwardmcguire]

Hello, I have a presentation tomorrow and I have two problems which I can't seem to fix/figure out. The first problem is I want to enable the percentages on my bar graphs and it won't let me do that, it only lets me put the actual number. Here is a picture to better understand what I mean:


I want to turn those points I have circled to show the percentage instead of the actual number.

The second problem is for the overall data. The survey was mostly yes/no questions, but one question was a 1-5 rating, and it throws off the whole size of the graph. Here is a picture to help give you an understanding of what I mean:

Do you see what I mean in terms of how small all the bars are (yes/no bars) are because of the 1-5 bars needed for that one question? Is there a way to fix this? Any help at all is greatly appreciated.
