by the various errorbar styles. In the default situation, gnuplot expects to see three, four, or six numbers on each line gnuplot error bars style of the data file -- either (x, y, ydelta), (x, y, gnuplot error bars histogram ylow, yhigh), (x, y, xdelta), (x, y, xlow, xhigh), (x, y, xdelta, ydelta), or (x, y, xlow,

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 xyerrorbars 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

So, for the error http://stackoverflow.com/questions/10684182/gnuplot-with-errorbars-plotting bar, I would need the bar at the x axis value 31, with the error bar start at (second column value)-(third column value), and end at (second column value)+(third column value). I tried the following: plot "file.txt" using ($1-$2):1:($2+$1) with errorbars but the result is inappropriate. Any help? plot gnuplot share|improve this question asked May 21 '12 at 11:16 user506901 3343613 add a comment| 2 Answers 2 active oldest votes up vote 16 down vote accepted You need x:y:err, so try plot "file.txt" using 1:2:3 with yerrorbars You may instead want candlesticks. These are generally a box with error bars extending out of the top and bottom, but setting the mins and maxes the same should give you boxes of the required size: plot "file.txt" using 1:($2-$3):($2-$3):($2+$3):($2+$3) with candlesticks share|improve this answer edited May 21 '12 at 14:13 answered May 21 '12 at 11:38 Phil H 12.6k54083 Thanks.
