Currently, to have default font size values for my graphs I do the following:
However it will only do the job for Plot function. There are many others (like ListPlot, LogPlot, etc). Of course I could manually add them in the list given as first parameter here.
But I would like to know if there is a way to say something like "for all functions that uses the option "TicksStyle" put TicksStyle->Directive so that it will be done once for all for all the possible function using it ?
