C++ API

: shading (type)

: shading (hax, type)

Set the shading of patch or surface graphic objects.

Valid arguments for type are

"flat": Single colored patches with invisible edges.
"faceted": Single colored patches with black edges.
"interp": Colors between patch vertices are interpolated and the patch edges are invisible.

If the first argument hax is an axes handle, then plot into this axis, rather than the current axes returned by gca.

See also: fill, mesh, patch, pcolor, surf, surface, hidden, lighting.
