Error List Plot with Legends
Any suggestions on how to add a legend in an ErrorBarPlot? The simple PlotLegend option that used to work on ListPlot doesn't work here. Needs["ErrorBarPlots`"]; Needs["PlotLegends`"]; ListPlot[{Table[i, {i, 10}], Table[i + 3, {i, 10}]}, Joined -> True, PlotLegend -> {"A", "B"}] ErrorListPlot[{Table[{i, Ran... 22 Feb 2010 19:48

Exporting interactive 3D objects from Mathematica to PDF documents
Hi guys. Is there anyway I can create a 3D object in Mathematica and include it in a PDF file for interactive display? There is a Latex package called movie15 that allows embedding of 3D objects into PDF files and allows the user to interactively manipulate them. The documentation for movie15 as of 2009 st... 22 Feb 2010 19:48

Digitizing plots with Mathematica (i.e. extracting data points from
I've just written a blog post showing how to make a plot digitizer using Mathematica. It may be of interest to other Mathematica users particularly anyone who wants to extract some data out of plots. barChartDigitizer[g_Image] := DynamicModule[{min = {0, 0}, max = {0, 0}, xmin = -1., xmax = 1., pt = {0, 0}, ... 22 Feb 2010 04:09

Handheld mathematica
How about an iPad front-end app that accesses the Mathematica kernel on desktop? This lets me take my most powerful tool on the road and save my back and neck from lugging laptop. Daniel ... 25 Feb 2010 02:35

Cursor blink off in Linux Mathematica?
Dear group, is it possible to set cursor blink of in Linux versions of Mathematica? In Windows XP, there is CursorBlinkRate in registry, and setting it to -1 makes the cursor non-blonking in most windows programs, including Mathematica. But could this be achieved on Linux? The windows tip is from: http://w... 22 Feb 2010 04:09

Loops in Manipulate
In trying to set up Manipulate wherein the controlled variable is part of the iterator in a Do loop or the target in a While loop, I get sliders but no other output than {Null}. ??????????? ... 23 Feb 2010 09:01

Manipulate piecewise functions,
a = {1 2 3 4 5 6} The goal is to plot a piecewise function corresponding to each of "a" values, with manipulate where control variable is p, and the function for plot y versus x is: y=x-p for x-p<a, and (x-p)^2 for (x-p)>=a i.e. 6 plots getting manipulated simultaneously. I am new to Mathematica and this might ... 24 Feb 2010 06:25

multiple variables in pure function used in map.
Hi, All Is there a way to use multiple variables in pure function with map. What I want to do is like this: ab = {{1, 2}, {2, 3}, {3, 4}}; (#[[1]] + #[[2]]) & /@ ab {3, 5, 7} Instead of refer to elements in list I want to use multiple variables in pure function. something like this: ab = {{1, 2}, {2,... 21 Feb 2010 04:54

some question about "FourierTransform"
I am a user of both Mathematica ver 4 and 7 On ver 4, "PrincipalValue->True" is recognized and works fine for "FourierTransform". But on ver 7, this seems to be no longer recognized (But it looks doing something compared to evaluation without "PrincipalValue->True", though not satisfactory) For the purpose to ge... 20 Feb 2010 08:00

Poisson-Boltzmann equation
Does anybody know any Mathematica resources for solving non-linear Poisson-Boltzmann equations for some simple geometries? I need a quick answer (responding to a paper's referee) and do not have time to get into the whole business myself :( Thanks Michael On Fri, Feb 19, 2010 at 3:35 AM, michael partensky ... 20 Feb 2010 06:55
