See "help errorlines". And maybe
by the various errorbar styles. In the default situation, gnuplot expects to see three, four, or six numbers on each line
Gnuplot Error Bars Color
of the data file -- either (x, y, ydelta), (x, y, gnuplot xyerrorbars ylow, yhigh), (x, y, xdelta), (x, y, xlow, xhigh), (x, y, xdelta, ydelta), or (x, y, xlow, gnuplot boxerrorbars 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 http://gnuplot.10905.n7.nabble.com/plot-with-connecting-lines-and-with-errorbars-simultaneously-td4548.html 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 http://gnuplot.sourceforge.net/docs_4.2/node140.html 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

This is my gnuplot code: set terminal postscript eps color set output '| epstopdf --filter --outfile=plot.pdf' set xlabel "Simulation days" set xtics nomirror set ylabel "Time (seconds)" set ytics nomirror set logscale y set key left top plot "data1.csv" using 1:($2/1000):($3/1000) with yerrorbars pt 5,\ "data2.csv" using 1:($2/1000):($3/1000) with yerrorbars pt 7 The error bars from gnuplot error bars the first plot are different from the second one. The first line is solid, but the second is dotted. Its possible to define the style of the error bar? plot gnuplot share|improve this question asked Jun 9 '14 at 9:22 mariolpantunes 597822 Oh, wow, did not know about the output '| ...'. +1 for teaching me that :) –Bernhard Jun 10 '14 at 15:01 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted In your case, the easiest option is to use the solid terminal option to have only solid lines: set terminal postscript eps color solid lw 3 set output '| epstopdf --filter --outfile=plot.pdf' set samples 10 set xrange [0:10] unset key plot '+' using 1:1:(0.2*$1) w yerrorbars, \ '' using 1:(1.5*$1):(0.1*$1) w yerrorbars Result with 4.6.4: Alternatively, you can use lt 1 lc 2 for the second plot, which selects the line pattern of the first linetype (which is solid), and the color of the second one: plot '+' using 1:1:(0.2*$1) w yerrorbars, \ '' using 1:(1.5*$1):(0.1*$1) lt 1 lc 2 w yerrorbars share|improve this answer answered Jun 9 '14 at 9:31 Christoph 29.5k72847 add a comment| Your Answer draft saved draft discarded Sign
