Plot Error Bars Log Scale


Very straightforward. –rcollyer Apr 4 '12 at 14:56 1 @rcollyer Thanks! A tag is like a keyword or category label associated with each thread. These guided examples of common analyses will get you off to a great start! Load package and make up a data set: Needs["ErrorBarPlots`"] data = [email protected][1, {10, 2}]; error = RandomReal[0.2, 10]; errorplot = ErrorListPlot[Partition[Riffle[data, ErrorBar /@ error], 2], Joined -> True, PlotRange -> All, have a peek here

DDoS ignorant newbie question: Why not block originating IP addresses? From the website: ErrorBarLogPlots.m is a package which adds log-scale plotting functions similar to the standard ErrorListPlot provided in Mathematica 6. Since I use Mathematica 9 the old library from Mathematica 6 with Errorlogplot does not seem to work. If you only saw the mean and error bars (which many scientists like to plot) without the raw data, you would be mislead.

Thank you. https://www.mathworks.com/matlabcentral/newsreader/view_thread/52022 Luckily for us it has an integer 0 so it is easy to avoid applying a pattern that distinguishes it from real numbers we need to deal with.

In contrast the geometric SD is not expressed in these units. It's CustomTicks package is a superior alternative to trying to set it up by hand.

BTW, semilog (y) doesn't look too bad doing as above, but I'm sure that's not good enough... First thing I tried was errorbar(x,y,e/2);set(gca,'xscale','log','yscale','log') but got "Negative data ignored". I tried to manually take the log of the data and then grab the tick-marks but that didn't work right data = [email protected][{10, 100}, {10, 2}]; error = RandomReal[20, 10]; logdata

If there isn't anything on TMW Code Central, I'd look at the errorbar function and see about fixing up the calculation of the error bars accounting for the x axis values. In other words, these error bars plot the geometric SD. Was the Boeing 747 designed to be supersonic? Play games and win prizes!

Of course, your error bars got log-scaled too. Careful with Offset - its 1st argument needs to be left a lone.
