Hi Jens, You need a proper input to plot3d (x and y monotonous with length n1 and n2, and z with size n1 x n2):
clear; clf(); plot3d([0 1],[0 1],[0 0; 0 0]) ce=gce(); ce.color_flag=0; ce.color_mode=5; // 5 = red; 1 = black Regards, Rafael From: users [mailto:users-boun...@lists.scilab.org] On Behalf Of Jens Simon Strom Sent: Saturday, November 12, 2016 12:00 PM To: Users mailing list for Scilab <users@lists.scilab.org> Subject: [Scilab-users] Facet color in Vers. 5.5.2 Hi Scilab experts, please help me to get the facet black, not cyan. plot3d([0 1 1 0]',[0 0 1 1 ]',[0 0 0 0]') ce=gce(); ce.color_flag=0;// Help page says: "All facets are painted using the color index and method defined by color_mode" ce.color_mode=1//Help page says: "The color of the facet when color_flag value is 0" Index 1 should produce Black, but CYAN is delivered. //getcolor Regards Jens
