Hi, set the aspect ratio by hand, i.e., DisplayChannel = $DisplayFunction; If[$VersionNumber >= 6.0, DisplayChannel = Print]; (*fix for Mathematica 6& later*) Off[General::spell1]; Off[General::spell]; ClearAll[r]; vFEM = {{4., 0.054}, {7., 0.0395}, {10., 0.037}}; vexact = 0.1905*(1/r + r/100); rbeg = 4.; rend = 10.; pFEM = ListPlot[vFEM, PlotJoined -> True, PlotStyle -> {RGBColor[1, 0, 0]}, DisplayFunction -> Identity]; pexact = Plot[vexact, {r, rbeg, rend}, PlotStyle -> {RGBColor[0, 0, 0]}, DisplayFunction -> Identity]; Show[Graphics[AbsoluteThickness[2]], pexact, pFEM, TextStyle -> {FontFamily -> "Times", FontSize -> 12}, GridLines -> Automatic, Axes -> True, PlotRange -> All, PlotLabel -> "Radial displacement (black=exact,red=FEM)", Frame -> True, DisplayFunction -> DisplayChannel, AspectRatio -> 1] Regards Jens carlos at colorado.edu wrote: > The following extract exemplifies a plot technique I used to > combine ListPlot and a Plot under v 2.2.
