If I do for example [pnt, tri] = icosahedron162; bnd.pnt = pnt; bnd.tri = tri; ft_plot_mesh(bnd, 'facecolor', pnt(:,3)) it should use facecolor and plot a sphere that goes from blue at the bottom to red at the top. The values in pnt(:,3), i.e. the height in this example, should be assigned to the vertices and used for visualising e.g. the spatial distribution of the values over the mesh (think of a cortical mesh with source reconstructed power).

if already implemented, then it should also be documented...

implementation is there: key-value pair to use is 'vertexcolor', and an Npntx1 array. This has now been documented in the help
