I’m using the Ternary Chart to plot three variables of interest.
Technically, a ternary plot should have three variables that sum to a constant.
However, the domain of my variables includes negative values.
Now, in theory, the linear space of the domains of each of the variables could be mapped onto R => [0,100].
From this, we can then compute the sum and normalize each variable by this sum to produce a [0, 100] value for each of the axes.
The problem is, I lose the original domain values prior to the transformation.
So my question is, can I use negative values for the ternary plot?
