Origin Version (Select Help-->About Origin): 7.5 Operating System: Windows XP
I'm looking for any way to visulize different composition within a quaternary plot e.g. for the Fe-Ni-Al-Co system and to assign additional informattion by color coding.
Origin does not have a built-in Quaternary plot but you might consider using Origin to represent your data as a 3D-XYZ scatter plot with the 4th dimension color mapped to the scatter points.
