previous fontsize settings in plot now produce huge fonts

I have been using p.fontsize(20) a lot, but since the upgrade to 6.8, the same setting now produces HUGE font sizes, making the axes labels exceed the figure sizes. I wonder what happened there and how this could be fixed. I believe that some of the reason is the introduction of the new option axes_labels_size as mentioned here: http://ask.sagemath.org/question/2680...

Try this in a sage version before 6.7 and after 6.7:

P = plot(x^2, 0,2)
P.axes_labels(['Some value of x', 'Resulting value of y'])
P.fontsize(20)
P

Is there a way to put a one-liner at the start of my worksheets to get back the old behaviour without having to modify all P.fontsize(20) lines?

It's not a one-liner and not particularly elegant, but you can just wrap another layer around plot to put in another default.

def plot(*args,**kwargs):
    if "axes_labels_size" not in kwargs:
        # perhaps we should copy kwargs before modifying it?
        kwargs['axes_labels_size']=1.0
    return sage.plot.plot.plot(*args,**kwargs)

A slight architectural change to more easily accommodate requests like yours would be to rewrite sage.plot.graphics to initialize default values from a dictionary rather than in code. Then one could relatively easily monkey-patch the dictionary.
