Gnuplot Set Style Error Bars
Contents |
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 set bars ylow, yhigh), (x, y, xdelta), (x, y, xlow, xhigh), (x, y, xdelta, ydelta), or (x, y, xlow, error bars gnuplot 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 gnuplot error bars histogram 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 Standard Deviation
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
