Those bar-graphs are definitely not drawn correctly to scale.
194 is about 60% of 328, yet its graph is well below 50% of 328. Just eyeballing it, it looks more like 1/3.
Also 118 is about 60% of 194, but again, its graph is well below 50%
Finally, 118 is around 36% of 328, i.e slightly more than 1/3, yet its graph is well under 1/4 of 328's graph.
Here's a simple text-only representation, using X's in a mono-spaced font
Code:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 33 X's
XXXXXXXXXXXXXXXXXXX 19 X's
XXXXXXXXXXXX 12 X's
