Regarding the ylabel rotation, please provide a complete example. For  
me that default rotation for the ylabel is 90 degrees.

To change the default font, try adding the following the our ~/.octaverc

        set (0, "defaultaxesfontname", "Arial.ttf")
        set (0, "defaulttextfontname", "Arail.ttf")

You may continue to get font messages/warnings as the same fonts do  
not work will all output formals. For that reason, the default- 
defaults are

        set (0, "defaultaxesfontname", "*")
        set (0, "defaulttextfontname", "*")
