A test: Is there an illusion here?

I thought I saw some effect when I was looking at one of the graphs on the stats page for the blog. I’m not sure if the effect is real, or it was just me. I’ve created a small test to find out.

There are three graphs below, each with two bars of different heights. In each graph are also suggestive values for the heights of the bars. You have to say if you think the suggested values are right or wrong. There’s a poll at the end where you can enter your answers. Pick one option for each of the figures. I’ve hidden the results to prevent any biasing. I’ll put up the results when there have been enough votes.
