surf and mesh in new figure

hi,

im always struggling with surf (or mesh) plots. with normal plots i do:

figure
plot(x1,y1)

figure
plot(x2,y2)

and i get two figures (perfect!). but if i do:
figure
surf(x1,y1,z1)

figure
surf(x2,y2,z2)

the second surface plot 'overwrites' the first one (and the same happens with mesh(x,y,z)).
why/how is surf different from normal plot?
and how should i solve this?

What does

gcf

return? 2 after the second call, I presume?

Not sure why, but surf and mesh use low level calls only and begin w/ a
call new the function newplot() which may be behaving badly is my
conjecture...

The sequence performs as expected here w/ an earlier release (R12) so
I'd submit an official query to TMW as to why/when behavior actually
changed.

thanks for your help! actually it turns out the problem is my computer!!

if the figure windows open, there is no figure visible, but if i put it on full screen then the plot/surf becomes visible...

very strange and i suspect it has something to do with samsung... every samsung product i know has some weird glitches...
