You repeatedly display column (bar) graphs with truncated axes. This is well established to be a cognitively problematic visualization type: the “amount of ink” on a page projects sizes and draws attention.

At the same time, many of the points you are trying to convey really should have the kind of focus your truncated axes produce -- small enough but clearly significant variations that they won't be visible with a full axis.

Would you consider using a plot variation less heavily criticized? I would suggest something like a box-and-whiskers plot; or a violin plot to give a sense of the entire distributional shape.
