How can I transmogrify this figure for the [Generalized MVT](https://math.stackexchange.com/q/296176)? If $f$ and $g$ are continuous
on the closed interval $[a, b]$ and differentiable on the open interval $(a, b)$,
then $\exists$ $c ∈ (a, b)$ $
\cfrac{f'(c)}{g'(c)} = \cfrac{f(b)-f(a)}{g(b)-g(a)}$.
~~Please don't just change the t-axis to $g(t)$.~~

Please answer with a picture. Please edit my scan, and draw or write in what you mean. Don't just change the t-axis to $g(t)$.
