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
