"Max" appears to be unrelated to the actual graph

According to this the "max" is 37ms, but looking at the graph we can clearly see several spikes up into 50ms range. The demo gif in the README.md has this same problem.

I was just digging into this, nice eyes! I suspect it's a matter of aliasing or rounding on the part of the tui::Chart widget. I'm not seeing the values in the histogram matching what's being displayed, so it doesn't seem like an issue with the data calculation:

ah yup, it's weirdness with the label rendering and not the data itself. I have an approximate fix in #116 , the math here is interesting with the Chart padding.
