Matching axes scales

Question

I have 3D data plotted using the \'plot3\' function. I would like to constrain the Y and Z axes such that they are equal in scale. The X axis should be automatically scaled

Answer 1

Try daspect.

plot3(5*rand(10,1),10*rand(10,1),rand(10,1))

tmpAspect=daspect();
daspect(tmpAspect([1 2 2]))

daspect() returns the current aspect ratio as produced by axis 'auto'.

daspect(tmpAspect([1 2 2])) then enforces that y and z have the same scale.

Answer 2

How about

axis equal

or even

axis tight
axis equal

both after the plot has been drawn.

Is this what you mean?

Type help axis at the Matlab command prompt for more capabilities of the axis function.
