We are adding in some additional comments into the file and will upload later today.
Thanks for the great feedback from everyone on these diagrams! Using the new ternaryX and ternaryY functions have proved to be very useful.
One of the differences with the older templates is that the diagram is centered at 0,0. Since zero is a special number on the cartesian coordinate system, DataGraph will set the padding to snap to zero. This may be a bit in the weeds, but the end result is that you can modify size using the Canvas settings in the same native way you would with any DataGraph image.
We will also make a video demo when we get this finalized.
