Alejandro, One way to handle this is to convert your data to log values for x, then plot with MultipleListPlot and then use a LogScale for the frame edge. There are other more fancy ways if you want to add fitted curves. I don't think you want the first data point at x = 0, because you can't fit that on a log scale. Needs["Graphics`MultipleListPlot`"] Needs["Graphics`Graphics`"] Needs["Graphics`Colors`"] data = {{{0., 1}, ErrorBar[{0., 0.}]}, {{0.13, 0.899147}, ErrorBar[{-0.0158522, 0.0158522}]}, {{0.37, 0.585022}, ErrorBar[{-0.0403446, 0.0403446}]}, {{0.7, 0.391931}, ErrorBar[{-0.0720489, 0.0720489}]}, {{1.11, 0.319891}, ErrorBar[{-0.0331414, 0.0331414}]}, {{3.07, 0.0951042}, ErrorBar[{-0.0216138, 0.0216138}]}, {{5.97, 0.0720401}, ErrorBar[{-0.0100861, 0.0100861}]}, {{22.24, 0.0461106}, ErrorBar[{-0.0158478, 0.0158478}]}}; data2 = Drop[data, 1] /. {{x_, y_}, err_ErrorBar} :> {{Log[10, x], y}, err}; MultipleListPlot[data2, Frame -> True, FrameTicks -> {LogScale, Automatic, None, Automatic}, FrameLabel -> {x, y}, Axes -> False, PlotLabel -> "Log-Linear Multiple List Plot", Background -> Linen, ImageSize -> 450]; David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Carabe - Fernandez, Alejandro [mailto:a.carabe at imperial.ac.uk] To: mathgroup at smc.vnet.net Hi, this is the only support address I find in the Wolfram webpage. If I need to redirect this question to someone else, please let me know. Here is the question: I want to plot the following data set on a Log-Linear format: { {{0., 1}, ErrorBar[{0., 0.}]}, {{0.13, 0.899147}, ErrorBar[{-0.0158522, 0.0158522}]}, {{0.37, 0.585022}, ErrorBar[{-0.0403446, 0.0403446}]}, {{0.7, 0.391931}, ErrorBar[{-0.0720489, 0.0720489}]}, {{1.11, 0.319891}, ErrorBar[{-0.0331414, 0.0331414}]}, {{3.07, 0.0951042}, ErrorBar[{-0.0216138, 0.0216138}]}, {{5.97, 0.0720401}, ErrorBar[{-0.0100861, 0.0100861}]}, {{22.24, 0.0461106}, ErrorBar[{-0.0158478, 0.0158478}]} } I know I have to use MultipleListPlot to plot this, but the problem is that Mathematica will return a Linear-Linear plot rather than a Log-Linear plot. By the way, I am using Mathematica 4.1. Thanks for your help, A.Carabe
