Yes, this is the intended behaviour.

What about calling g.dodata before start to work on h? Then the axis range
should be fixed (and a warning will be issued).
I didn't check whether this works. I coded it years ago and might be wrong on
whether this really works. But I would expect this "workfow" to be supported
and to solve your issue. Does it?
