axis labels and tick marks on scatter plots

[yamins81]

When doing comparisons between different metrics on the compare tab, it would be really important for there were units and if the axes were labeled with the chosen metrics. I don't see any units or tick marks on the plots that are easy to interpret.

Right now the plots are just too raw to really be tweetable or near-publication ready, and I think improving this will really improve the impact of brain-score.
