Hi:
I have a 2D triangulation data including vertices and connectivity, I want to color it with the value at its geometry center. I tried to add a "CData" but it is not recognized by "triplot" function:
Tri=triplot(DT.ConnectivityList,DT.Points(:,1),DT.Points(:,2),'CData',cm);
where DT is the triangulation objective, and cm is the color at each triangle center.
is there anyway in Matlab can do this?
Thanks!
Yu

Read about trisurf. Also have a look on patch. You can use any of the two to achieve what you want.

Tri=trisurf(DT.ConnectivityList,DT.Points(:,1),DT.Points(:,2),cm);
I am assuming that cm is a column array with same number of rows present in Dt.Points.
