Here you have two graphs, one -- graph of the function y=f(x) on the coordinate plane with axes x and y, another -- graph of the function on the coordinate plane with axes y and x.
Actually, these graphs are graphs of the same function, only axes are changed.
It makes the sense to graph to functions and
on the same set of axes, not graphs of the same function
and
on the different set of axes.
