How can that solution be modified so as to allow defining some functions to effect the TraditionalForm[HoldForm[...]] construction? For example, something like the following -- which is not robust: mathForm[expr_] := TraditionalForm[HoldForm[expr]]; xyLabels[x_, y_] = {mathForm[x], mathForm[y]}; fnLabel[{p_, q_}] := Text[mathForm[y = f[x]], {p, q}]; Plot[x^2, {x, -1, 1}, AxesLabel -> xyLabels[ x, y], Epilog -> fnLabel[{0.65, 0.75}]]; The trouble is shown by preceding the above input by, say: x = 100; f[x_] := Sin[x]; y = "hello"; Then the axes labels are 100 and "hello", and the Text displayed with the plot is sin(x).
