如何更改python mayavi对象中的间距值？

Question

I have plotted a few things using mlab in Python mayavi. For some reason, when I create an isosurface by doing:

s = mlab.contour3d(xx, yy, zz, data, contours=[1.5], figure=fig)

it creates one with a spacing (0, 0, 0.5) when it should be (0.5, 0.5, 0.5). How do I set that spacing in my script without having to manually go into the figure's pipeline (show below)?

我能够通过以下方式自己弄清楚：

fig.children[-1].spacing = np.array([0.5, 0.5, 0.5])
