Bug summary

When plottingPoly3DCollection withaxlim_clip=True, the patch is split into multiple patches and renders poorly.

I am leaning towards this being the "correct" behavior, but want to open the bug report to document it and see if anyone has a solution that solves this cleanly.

Code for reproduction

importnumpyasnpimportmatplotlib.pyplotasplt# Generate some random datanp.random.seed(42)x=np.arange(10)y=np.zeros_like(x)z=np.random.randint(5,10,10)fig,ax=plt.subplots(1,1,subplot_kw={'projection':'3d'})ax.fill_between(x,y,z,x,0,0,axlim_clip=True)ax.set_xlim(0,8)plt.show()

Actual outcome

Expected outcome

Additional information

There are two workarounds for this particular example:

1. Restrict the data to the x=[0, 8] range before plotting.
2. Usefill_between with thequad mode like so:

ax.fill_between(x,y,z,x,0,0,axlim_clip=True,mode='quad',shade=False)
