Set default fontsize in figures

Hello,

I am trying to setup a startup file with default parameters so that all my figures are consistent (same fonstize, linewidth, interpreter, etc). Everythings work fine except for the fontsize!

I would like the fontsize of the ticks on the x- and y-axis to be sligthly smaller than the label and legend fontsize. I used the following command in my sartup.m file:

set(groot, ...
    'defaultAxesFontSize',14, ...
    'defaultTextFontSize',20, ...
    'defaultLegendFontSize',20, ...
    )

It usually works when I manually use those lines (with gca and not groot) after every figure. But here, 'defaultAxesFontSize' sets the fontsize of all of the figure, it seems that 'defaultTextFontSize' and 'defaultLegendFontSize' do not change anything to the figure (even if I put the fontsize to 40 or higher).

Do anyone know why it does not work ? Thanks !

Anthony.
