How to disable perspective in mplot3d?

This is now official included since matplot version 2.2.2 Whats new | github

So for plotting a perspective orthogonal plot you have to add proj_type = 'ortho' then you should have something like that:

fig.add_subplot(121, projection='3d', proj_type = 'ortho')

Sort of, you can run this snippet of code before you plot:

import numpyfrom mpl_toolkits.mplot3d import proj3ddef orthogonal_proj(zfront, zback):    a = (zfront+zback)/(zfront-zback)    b = -2*(zfront*zback)/(zfront-zback)    return numpy.array([[1,0,0,0],                        [0,1,0,0],                        [0,0,a,b],                        [0,0,0,zback]])proj3d.persp_transformation = orthogonal_proj
