what 's different between axis square and axis equal in matlab ?

when I plot or surf, what's different between axis square and axis equal ?

Answer 1

[Mahdi]

From this page:

axis equal sets the aspect ratio so that the data units are the same in every direction. The aspect ratio of the x-, y-, and z-axis is adjusted automatically according to the range of data units in the x, y, and z directions.

axis square makes the current axes region square (or cubed when three-dimensional). This option adjusts the x-axis, y-axis, and z-axis so that they have equal lengths and adjusts the increments between data units accordingly.

Do you know the formula to set your axes to be square?

[Walter Roberson]

Could you explain your question further?

[Narin Deveci]

well, I am making a barchart with the data I have, and it says 'set the axes to be square, and save a pdf copy of the figure names ‘PhaseAmpMod.pdf’. I dont fully understand it, so not sure I am explaining well.

[Walter Roberson]

axis square

Hi, I have a 3D plot, I set axis([-100 100 -80 120 -50 150]) followed by axis equal. That means I have equal range of data in all directions and figure should look like a cube but hight looks larger than bottom witdhs on my screen? why?
