This plots it both ways: plot1 = Plot[Sin[x], {x, 0, 3Pi}]; plot2 = plot1 /. Line[{a__}] :> Line[Reverse /@ {a}]; Show@plot2 To plot it only the second way: Show[Plot[ Sin[x], {x, 0, 3Pi}, DisplayFunction -> Identity] /. Line[{a__}] :> Line[Reverse /@ {a}], DisplayFunction -> $DisplayFunction] Bobby -----Original Message----- From: Gregory Lypny <gregory.lypny at videotron.ca> To: mathgroup at smc.vnet.net Subject: [mg41516] Switching x and y axes in a plot Hello everyone, I'm new to Mathematica, so I hope you'll forgive my first couple of naive questions. I've used Plot to graph a parabola as follows: Plot[ax^2 - 2bx + c, {x, xMin, xMax}]. Is there any way to plot the function so that y appears on the horizontal axis and x on the vertical? (I realize the parabola part is uninteresting; it's actually the solution to a standard problem in financial economics involving the minimization of investment portfolio risk for a given expected return.) Another plot-related question, if I may: do all plots require the specification of a domain as {x, xMin, xMax}? For example, how would I create a scatter plot of experimental data where I have a long two-column list or matrix consisting of x and y observations where the data determine the domain and range?
