I am not sure I understand what you mean by "make the y-axis point downwards". I am guessing you want the increasingly positive tick values to appear toward the bottom of the page. If I have this right perhaps you will find the following satisfactory Plot[-Log[Abs[x]], {x, -2, 2}, PlotRange -> {Automatic, {-1, 3.5}}, Axes -> False, Frame -> True, PlotPoints -> 100, FrameLabel -> {"x", "y"}, FrameTicks -> {Automatic, Transpose[{ Range[0, 3], Range[3, 0, -1]}], {}, {}}]; -- To reply via email subtract one hundred and four
