How do I offset the origin of one axis in PyPlot Plot3D

I am doing a 3D plot with Plot3D

using PyPlot

< code that computes x1, x2, x3 >

plot3D(x1,x2,x3)
xlim(6378237-1000,6378237+1000)
ylim(-1000,1000)
zlim(0,1000)

Instead of setting the limits of the x-axis with xlim() I would like to set the origin of the x-axis to be 6378237. Which Julia PyPlot command does this?

(It is surprisingly difficult to find the answer on the web)

This SO thread may be of help to you if I understood your question correctly:

Every command you type in matplotlib/pyplot should work as it is with PyPlot.jl. If it doesn’t, you can open an issue on GitHub.
