Hi,
I'm trying to make a set of plots that are slightly different using function graphics. Is there any way to set the various graphics properties once and have them apply to all of the plots (i.e., change the defaults)? I know how to use system variables for direct graphics, but so far have defined the properties over and over again for these plots and can't find a way to do otherwise.
Thanks!

You can define an anonymous structure that describes your style, and pass that
to function graphics routines using the _EXTRA mechanism
mystyle = {thick: 3, color: 'red', xtitle: 'happiness', ytitle: 'joy'}
p = plot( [0, 1], _extra = mystyle)
This way, you define your properties once (in the structure) and use them
in all of your plots.
All the best,
David

It's something to do with the inexorable passage of time.
Sigh.
