So, http://stackoverflow.com/questions/10684182/gnuplot-with-errorbars-plotting for the error 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).

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 12.6k44083 Thanks.

Both error bars x and y dimensions have high/low errorbars, that is the errorbars are not symmetric, so each data point uses six values (x,y,xlow,xhigh,ylow,yhigh). Gnuplot's man pages say this is possible and I've found examples on the net - both cases suggest using data files with six records for each data point (the (x,y,xlow,xhigh,ylow,yhigh) format) but I can't for the life of me get Gnuplot to behave. The best I can do when plotting a single test point (1.0 3.0 0.25 0.5 0.25 gnuplot error bars 0.5) is to get a plot of the test point with disembodied errorbars floating in nearby space. gnuplot share|improve this question edited May 31 '12 at 1:40 Dan 5,16652056 asked May 30 '12 at 21:11 user1427035 1612 Can you post some example code/data which illustrate your problem? –andyras May 30 '12 at 21:43 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote The reason your error bars are "disembodied" is that your x (1.0) is not between xlow (.25) and xhigh (.5). Your y (3.0) is also not between your ylow (.25) and yhigh (0.5). If you want the lows and highs to represent the difference from the central variable, you should use a command like this: plot "test.dat" u 1:2:($1-$3):($1+$4):($2-$5):($2+$6) with xyerrorbars t "test point" Running this on your test file, I get the following plot: share|improve this answer answered May 30 '12 at 23:39 Dan 5,16652056 1 I wonder why it is implented this way in gnuplot. Errorbars should never be "disembodied" and it's more work to write value + error than just error. –con-f-use Apr 27 '15 at 15:33 @con-f-use: Error bars could in general be asymmetric. –Dan Jul 26 at 22:13 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as
