Annotation of scatter plots

[nikohansen]

The x- and y-labels of the scatter plots should give the algorithm name instead of "log10(# evaluations)".

Rationale: without knowing the annotation we gain (almost) zero information from the plots. Even with lots of experience, I always have to check the caption several times to be certain which algorithms is on which axis.

Why not have both?

Are we happy with the current output?

I remember that we said at some time to decrease the font size in the axis labels.

I think we came to the conclusion that it depends on whether you are looking at (1) separate plots (or at plots via the html page) or (2) a table of small plots in the paper. Since we want to support (2), we decided on keeping the large fonts.

[nikohansen]

The fontsize of the labels must IMHO be slightly smaller: they should not visually dominate the title.

The latest code in the development branch addresses the above. A new issue to adapt the LaTeX templates---if needed---has been added (#1962).
