axis font sizes

[Francis Poulin]

I recently figured out how to change the font of the x,y labels and  
the title using something like

set (0, 'defaulttextfontname', '/Library/Fonts/Arial');

where I have a file called Arial.ttf in the above mentioned directory.

When I export the figure as a png those fonts look great but the axis  
fonts still look awful.  Is there a similar command that will change  
the axis font and size?

Also, while were at it, where can someone find a list  of figure  
properties that someone can alter with set?
