All,
Is there an "axis equal" command for mplot3d?
D.
Unfortunately i have not found such a function as of yet and the function
that sound close to it (aspect) only controls the windows aspect ratio
Fortunately there is a quick and dirty work around
I have found the following to be useful
Assuming you have X Y Z matrices made using meshgrid or some other means
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = Axes3D(fig)
u = np.linspace(0, 2 * np.pi, 100)
v = np.linspace(0, np.pi, 100)
x = 10 * np.outer(np.cos(u), np.sin(v))
y = 10 * np.outer(np.sin(u), np.sin(v))
z = 50 * np.outer(np.ones(np.size(u)), np.cos(v))
ax.plot_surface(x, y, z, rstride=4, cstride=4, color='b')
Xstart=(x.min())
Xend =(x.max())
Ystart=(y.min())
Zstart=(z.min())
Scalex=(Xend-Xstart)
ax.set_xlim3d(Xstart,Xstart+Scale)
ax.set_ylim3d(Ystart,Ystart+Scale)
ax.set_zlim3d(Zstart,Zstart+Scale)
plt.show()
again I have made the assumption that the plot is "squarish" in the x and y
direction, a more robust version would test to see which is the biggest
scalex,scaley,scalez center the other axis value but again i just coded this
in 5 min as an example
