Is it possible to create a 3D ternary plot that looks similar to the current 3D trajectory plot, but with the triangular base? Currently we have a series of ternary plots at different temperatures and would like to see what the surfaces look like by combining this data into one 3D plot.
Thanks for the reply. The only problem with merging the ternary plots into one multi-layered plot is that we have a little too much data. The information density of the plot would probably confuse me. What I have been able to do is to convert from the ternary coords back to normal x-y coordinates and then do a normal 3D trajectory plot of all the data. The ternary data (x,y,z) can be uniquely mapped back and forth to normal 2D coordinates (x,y), which then allows me to use the z-coordinate as temperature. This can easily done reversibly with scripts. Color coding of the z-variable (temperature) is helpful. The only remaining problems are the inability to fit the points with a surface in 3D. This can be done a little bit by adding trajectories that show the phase boundaries. The other thing I may try is to allow the data reader to automatically convert the x,y data (ignoring temperature) back into my original 3D coordinates (which in this case is the composition of a 3 component alloy). Hopefully after rotating these plots around for a while and staring at them, I'll come to some better understanding of my research.
There is no way to produce a 3D-trajectory plot on a triangular base, but you might consider this:
You state that you already have a series of ternary plots at different temperatures. How about merging those graphs into a single ternary plot with each layer (temperature) identified by a unique symbol and/or color? You might even assign colors according to a blue, purple, red, orange, yellow, etc. color scheme to make viewing your data more intuitive.
3D ternary plots?
