Winston plot layout: axis labels, axis numbers, and aspect ratio

Hi there, I am trying to improve the design of some of my graphs using Winston but I am facing some troubles:

  • The power in the units of the axis labels looks too big and high, it there any way to change the size so that it will look nicer? See Figure
  • How can I change the numbering format in the axis so that all numbers show the same style (either power of ten or not, but not mixing both styles). See x axis on Figures
  • When changing aspect ratio in left figure I need to have the same figure size as in right figure, how can I do that?

This will seriously improve the look of the figures.
Below are the figures and the code.
Thanks in advance!
