aplotnikov	Posted - 08/19/2020 : 04:40:05 AM Origin Ver. and Service Release: Pro 2020b (64-bit) 9.7.5.184 Operating System: Windows 10 Hello, Is it possible to display (to turn on/off) contour lines on a 3d surface using programming interface (LT or OC)? Now I can do it only via dialog box: Unfortunately I haven't found any correspoding property of the layer.cmap object. What I need finally: I would appreciate any helpful advice. Regards, Alexei

aplotnikov	Posted - 08/19/2020 : 5:10:34 PM Thanks for your reply! Unfortunately it doesn't work at all. I tried to use this method before asking for help here. Moreover the property corresponding the checkbox "Self" still remains a secret. Does it matter if the surface represents a 3D parametric plot? It is not an idle curiosity - contours are very helpful in this particular case, but I have to generate (via LT script) each time a new 3d surface using different parameter sets.
Chris D	Posted - 08/19/2020 : 10:43:35 AM I fear the best you are going ot get in terms of showling hiding contour lines is layer.cmap.showLines(method); // See below layer.cmap.updateScale(); where: method = 1, show the lines only on the major levels. method = 2, show all contour lines. method = 3, hide all contour lines. That shows/hides lines but it doesn't appear to have any impact on that checkbox. It seems that that exact checkbox isn't LabTalk accessible. Note you may have to refresh the graph after running layer.cmap.showLines(method);. Thanks, Chris Drozdowski Originlab Technical Support

See: https://www.originlab.com/doc/LabTalk/ref/Layer-CMap-obj Could you please tell me, which exactly propeties correspond "Enable Contours" and "Self" checkboxes? I can change line style, line width, etc., but I cannot turn contour lines on/off programmatically.
