It's even terrible for what it is. If you look at the scale bars background, the scale shifts to preserve the length of the largest bar. This makes sense if you're just looking at one image but when going time to time it means the motion of each bar is distorted. A bar could shrink while gaining in percentage if the maximal bar is growing at a faster rate... What? Why?!?
