I do not fully understand, what (yAxis.min, yAxis.max) == (None, None)
is supposed to do. But I think you just want an easy way to access
positions in the graph. For that you can use the graphs pos() and
vpos() methods. (Note, that the pos() method can be only be used after
the dolayout() method was called when the axis ranges are adjusted
automatically.) But to get the upper right corner, you can just use
x, y = h.vpos(1, 1) ...

I'm not quite sure whether I totally misunderstood your question, so
please, ask again, when I was pointing towards something totally
uninteresting to you ...
