Histograms
ctioga now (from version 1.4) supports the use of error bars. Using
the file errorbars.dat, we can demonstrate
this feature:
ctioga --xpdf --margin 0.2 errorbars.dat@1:2:3
The look of the error bars can be tuned to suit one’s need:
ctioga --xpdf --error-bar-color DarkRed \
--error-bar-transparency 0.6 \
--margin 0.2 \
errorbars.dat@1:2:3
