Both 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 http://stackoverflow.com/questions/10824336/gnuplot-asymmetric-xy-errorbars 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 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 5,19652156 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 5,19652156 1 I wonder why it

Lemme test it real quick! –Dynelight Jul 12 '12 at 18:58 What does the '($0-.05)' in ($0-.05):4:5:xtic(1) represent? I know that '4' is telling the box to use the 4th column. '5' is telling the error bar to use the 5th column as the delta for
