I love that the data are showing something as well, that restaurants may not care how many violations they pick up inside the grades, but they try really hard not to pick up the violation that would take them over the line from one grade to the next one.

I agree with the arrow observation. Centering the axis-text is enough to communicate the intent.

Like Derek, I think it's interesting that there's such a sharp drop-off between low-scoring As and high-scoring Bs -- very suspicious. I don't know anything about how these gradings are done, but I would guess that the inspectors have more control over the exact number of violation points than the restaurants do. That makes we wonder why inspectors appear to tip the scales to keep restaurants one or two points short of a downgrade from A to B. Seems akin to grade inflation.

I have found the information in your blog post to be very useful and hope more are on the way. It's definitely one of the more easy to read ones that I've came across.

Very useful information to analyze a bar graph. I printed it to show it to my students. I stumbled on this nice post while searching for bar graph explanation for my students. It's really an awesome piece of info for grade eight statistics students to know all about a bar graph.

In case to axis titles, I think if they were centered without arrows,were better.

Any how, great post and keep it up.
