Issue with hggroup and zlim

[David Bateman]

I'm trying to implement line series objects, and with the current hg 
repository I see that

z = [0:0.05:5]; h =  plot3 (z, exp(2i*pi*z));

works fine, but

z = [0:0.05:5]; hold on; hg = hggroup(); h =  plot3 (z, 
exp(2i*pi*z),'parent',hg);


doesn't. Note that the "hold on" is need to avoid the hggroup being 
cleared. The result is that the zlim is [-0.6,0.6] when it should be 
[-1,1]. I took a quick look at graphics.cc and I can't see the reason 
for this issue. Perhaps Michael or Shai can. For now I'm just going to 
ignore it and go on with the line, etc series implementation.

regards
David
