如何在 GNU Octave 中设置轴大小？

Question

I am plotting a 3d surf plot in Octave and I want the z axis to be between 0 and 10. Can you please tell to to set axis to be between 2 values. The function ranges between 0 and 8 in z axis, but I want the z axis to be from 0 to 10.

Answer 1

Use the zlim command.

zlim([0,10]);

Or, the axis command with 6 arguments, but in that case you'd have to specify limits for X and Y too.

Here's an example

t = 0 : 0.1 : pi * 12;
x = cos(t); y = sin(t); z = t / pi;
plot3( x, y, z );
zlim([0,20]);
