Conflict in surf command between zscale and zlim?

Hi all,

I'd like to plot several 3D surfaces with semilog scale on z-axis, but also set the z-axis limit to be the same, so I do:

set(gca, 'ZScale', 'log')
axi_lim = [0, err0];
zlim(axi_lim)

The z-axis is semilog as I want, but the axis limit is different, like this

How can I make all the z-axis exactly the same? Many thanks!

See if this addition does what you want:

set(gca, 'ZScale', 'log')
axi_lim = [0, err0];
zlim(axi_lim)
axis tight                                  % <— ADD THIS LINE HERE

Hi,

I added this command into the script, it seems not working.

Z-axis is still different.

I don’t have the rest of your code to experiment with.

See if this syntax change works:

axi_lim = [0, err0];
set(gca, 'ZScale', 'log', 'ZLim',axi_lim)
axis tight

This can work when a direct call to the zlim function fails.
