Hi,
Sorry for the late response. Thanks for the help. So I read the documents and managed to get a gradient even if it's not exactly like the figure.

draw lmt_shade [
path = (z0--z4--z5--z1--cycle),
direction = "left",
alternative = "linear",
colors = {"black", "lightgray"},
] ;

the general metafun(-s|-p) manual, the big one (>400 p. in the “print”
version, >600 p. in the “screen” version). Recommended!
