I definitely can if needed, but... it's not that the axis label doesn't 
fit, it's just that I'd like a little more white space. So it may not match 
up with standard rules, but it's for a specific purpose. Please let me know 
how to adjust it.

Also, might this interact with my choice of plot size prior to production, 
with:

win.graph(width = 10, height = 7)

So no ticks without labels, as specified by the user? The above generates 
only ticks with labels.

Excellent. thanks.
