two virtual machines with each other and have data of the following form: BENCHMARK VM1_TIME VM1_ERROR VM2_TIME VM2_ERROR I want to generate a barchart diagram from this data which should look like this: Could somebody provide the code how to do this? I know this kind of request is unbeloved, but I really need this and googled for something like 2 hours, without a satisfactoring result. Thanks in advance, Sven gnuplot bar-chart share|improve this question gnuplot error bars standard deviation asked Aug 19 '12 at 2:25 Sven Hager 1,14721022 1 What about sharing your data, or offering some mock data, to play with? –vaettchen Aug 19 '12 at 2:55 I do not have concrete data yet because I need to know in what format Gnuplot wants it. However, it is clear that I have 5 columns of data: 1) Benchmark name 2) Time it took VM 1 to compute it (in milliseconds) 3) Time it took VM 2 to compute it (in milliseconds) 4) Error of VM 1 times (in milliseconds) 5) Error of VM 2 times (in milliseconds) –Sven Hager Aug 19 '12 at 13:02 If you want help, you need to provide data in a way that can easily copied & pasted - dput( mydata ) is always good. It will also be a good idea to provide the code you have tried that got you close but did not work. This is not only a matter of courtesy but also helps to avoid misunderstandings in terms of data structure, objectives etc. –vaettchen Aug 19 '12 at 13:46 1 possible duplicate of adding error bar to histogram in gnuplot –mgilson Aug 19 '12 at 23:23 1 Of possible interest: Adding error bars on a bar graph in gnuplot. –chl Aug 21 '12

by the various errorbar styles. In the default situation, gnuplot expects to see three, four, or six numbers on each line http://gnuplot.sourceforge.net/docs_4.2/node140.html of the data file -- either (x, y, ydelta), (x, y, ylow, yhigh), (x, y, xdelta), (x, y, xlow, xhigh), (x, y, xdelta, ydelta), or (x, y, xlow, xhigh, ylow, yhigh). The x coordinate must be specified. The order of the numbers must be exactly as given above, though the using qualifier can manipulate the order and error bars provide values for missing columns. For example, plot 'file' with errorbars plot 'file' using 1:2:(sqrt($1)) with xerrorbars plot 'file' using 1:2:($1-$3):($1+$3):4:5 with xyerrorbars The last example is for a file containing an unsupported combination of relative x and absolute y errors. The using entry generates absolute x min and max from the relative error. The y error bar gnuplot error bars is a vertical line plotted from (x, ylow) to (x, yhigh). If ydelta is specified instead of ylow and yhigh, ylow = y - ydelta and yhigh = y + ydelta are derived. If there are only two numbers on the record, yhigh and ylow are both set to y. The x error bar is a horizontal line computed in the same fashion. To get lines plotted between the data points, plot the data file twice, once with errorbars and once with lines (but remember to use the notitle option on one to avoid two entries in the key). Alternately, use the errorlines command (see errorlines (p.)). The error bars have crossbars at each end unless set bars is used (see set bars (p.) for details). If autoscaling is on, the ranges will be adjusted to include the error bars. See also http://gnuplot.sourceforge.net/demo/mgr.htmlerrorbar demos. See plot using (p.), plot with (p.), and set style (p.) for more information. Next: Errorlines Up: Plot Previous: Zticlabels Contents Index Ethan Merritt 2007-03-03
