matplotlib window

[nbehrnd]

The statistics plot consists of multiple sub-plots. So far, calling for them opens
a new window which is to small to display them without overlap of the diagrams,
especially their captions. While the situation is better when allowing this window
is allowed to expand to wider dimensions, it were preferable its display already
would be without overlaps when starting. If a display of different scale is needed,
like for a poster, or a presentation (e.g., beamer in LaTeX) / print publication,
one still may use matplotlib's vector export (of the then full-window display) to be
scaled accordingly in programs like inkscape.
