Prism doesn't do this automatically, but you can make it do so with a bit of work. Plotting logs in Excel Plotting the logarithm of your results on a linear scale raises the following (minor) issues: A logarithm is a pure number - i.e., a number without physical http://birdsallgraphics.com/error-bars/error-bars-indicate.php

I updated and annotated my Excel spreadsheet (uploaded), that I'm now satisfied with, in case anyone wants to comment on it, or for future reference. logplot = ListLogPlot[ data, PlotRange -> All, AxesOrigin -> {0, 0}, Joined -> True ] I tried Show[logplot, errorplot, PlotRange->All] to see if it would plot with the scale and ticks While the mark is used herein with the limited permission of Wolfram Research, Stack Exchange and this site disclaim all affiliation therewith. If the value is 1000 and the standard error is 100, I would plot the error bars at log (|1000 + 100| + 1) and log (|1000 - 100| + 1).

How To Plot Error Bars In Origin From the website: ErrorBarLogPlots.m is a package which adds log-scale plotting functions similar to the standard ErrorListPlot provided in Mathematica 6.

I work in a genotyping lab part time (in addition to my full-time job, naturally) so I have familiarity, though not expertise, in the subject. How To Plot Error Bars By Hand The error bars are symmetrical in terms of the values they represent, but on a log scale the lower error bar is much longer. I wish to plot this as a column plot on a log scale (y-axis) with negative values below the zero baseline, positive values above, and with the errors indicated. their explanation LinkBack LinkBack URL About LinkBacks Register Help Remember Me?

A couple of questions: (Q1) Is it "better" to use log (base 10) or ln (natural) log transformations? (Q2) How would I present the error bars - would I log (or How To Plot Error Bars With Standard Deviation Opportunities for recent engineering grads. These error bars give you a good sense of how precisely you know the populationgeometric mean, but don't show the amount of scatter.

Plotting the decimal log of N on a linear scale would give the same distribution of points, but with the difference that what can be read from the graph would be Genes 1,2, and 12 have average fold changes that do not make sense. Hello - I am a genetics researcher. Source So the untransformed interval would be -0.15 +/- 1.21 = -1.36 to +1.06.

I have a series of data points with errors (standard errors), that I wish to plot as a column plot with error bars: GENE, AVG FOLD CHANGE, SE Gene1, 2193.10, 1200.74 How To Plot Error Bars In Excel Mac Any choice of logarithm will give the same shape, changing only the scale. Download the zip file and install it, then retry the Needs command. –Markus Roellig Dec 4 '12 at 9:40 1 This solution may no longer work correctly in version 8

We just told Prism to label the Y axis with antilogarithms to make the graph easier to understand, and added log spaced minor ticks to emphasize the logarithmic nature of the I continued pursuing this topic (there), as I was able to upload a MS Excel file, that contained my test data, plus annotations. Otherwise your log-scale will break - you cannot take log of negative numbers.
