  Dear all, 
  I'd like to do a ternary diagram with straight boundaries that defines areas in the diagram. I've found this one: http://originlab.com/fileExchange/details.aspx?fid=300 but I cannot see where the "boundaries" option is in origin. Thank you for your help, Agnese

                Posted - 08/22/2017 : 03:08:03 AM  Hi Agnese,
  In the sample opj you mentioned, multiple XYZ data have been plotted into the ternary coordinate as lines, we can call them "boundaries". You can download the opj file to have a check.
  Of course, just as Nikolay said, if you are plotting a ternary contour graph, you can add actual boundaries.  http://www.originlab.com/doc/Origin-Help/PD-Dialog-ContourInfo-Tab
  Please let me know if you have any problem.
  Thanks,

                Posted - 08/21/2017 : 1:57:18 PM  It seems to me that boundaries are available only for ternary colormap/contour (it is need to be XYZZ).
