What does that mean/where did you get that idea?

Need specifics; generalities don't do as my crystal ball is again in the
shop... :(

If you're referring to the tick labels, that's not true; you can make the
tick labels contain whatever information you want. _By default_ they only
display a few decimal places; but you can adjust them however you want.

x = 0:0.1:1;
y = x.^4;
plot(x, y);
yticks = get(gca, 'YTick');
set(gca, 'YTickLabel', sprintf('%1.12f|', yticks));

If you want to control the tick labels as you zoom, use the zoom mode
object's ActionPostCallback.

But note that if you want one pixel on screen to reflect a change in the Y
coordinate of your graph in the tenth decimal place, one or more of the
following must be the case:

1) Your Y axis must cover a very small range of Y values.
2) You have a LOT of pixels vertically on your screen.
3) The pixels on your screen are VERY small.

Now _there's_ a take on the posting that hadn't crossed my radar.

If so, gonna' have to send the crystal ball in yet again.... :)

He said 10 bits, not 10 digits. My monitor has 1200 vertical pixels, and if I really wanted to I could maximize a Matlab plot such that it makes use of almost all of them, certainly more than 1024.
