如何在matplotlib中设置轴不相等？

Question

I have the following figure in matplotlib . What i want to do is to have the scale of z-axis proportional to xy-axis.

and achieve something like this:

Answer 1

adding the following works:

ax.set_zlim(-1, 1)

correct figure

however i wonder if there is an alternative way!

Answer 2

There is more than one way you can do that;

Approach 1:

Setting the axis limit:

plt.zlim(tuple)

where

tuple = (z0,zf)

another way:

plt.zticks(array_1, array_2)

where

array_1 := range
array_2 := labels

Hope it helps!
