Maybe you should take agggrrrr and wow as two variables that belong to a function in the complex domain.
For every value in the x and y axis, you get another in the u and v axis (the image). The u axis would be for frustration and the v axis for content. Please, note that you need to make 2 two-dimensional graphs, since it's impossible to make a four-dimensional one.
Applying the Cauchy-Reinman theorem, you calculate the second derivatives of the function against x and against y. If the function is holomorphic, the derivatives are equal, and you'll be able to find the exact
value for the balance between frustration and content. And if you plot the function, you might get a heart shaped figure, centered between the imaginary axis and the real one
Cheers.
