Geometries with Dual Orientation¶

geom_linerange()
geom_pointrange()
geom_errorbar()
geom_crossbar()
geom_ribbon()

You can flip opientation of these geometries simply by flipping their positional aesthetics mapping.

Note: when flipping aesthetics, in certain cases, you will have to also change the position adjustment of the geometry.

For example, when flipping orientation from vertical to horizontal, position_dodge()
should be replaced with position_dodgev() (i.e. "vertical dodge").

Flipping an Errorbar¶

In [4]:

errorbar_v = geom_errorbar(aes(x='dose', ymin='len_min', ymax='len_max'), position=position_dodge(0.95))
errorbar_h = geom_errorbar(aes(y='dose', xmin='len_min', xmax='len_max'), position=position_dodgev(0.95))

gggrid([
    ggplot(err_df, aes(color='supp')) + errorbar_v + ggtitle("Vertical"),
    ggplot(err_df, aes(color='supp')) + errorbar_h + ggtitle("Horizontal")
])

p = ggplot(err_df, aes(y='dose', x='length', xmin='len_min', xmax='len_max', color='supp')) +\
    xlab("Tooth length [mm]")

gggrid([
    p + geom_crossbar(position=position_dodgev(0.95)) + ggtitle('geom_crossbar()'),
    p + geom_pointrange(position=position_dodgev(0.95)) + ggtitle('geom_pointrange()'),
    p + geom_linerange(position=position_dodgev(0.95)) + ggtitle('geom_linerange()'),
    p + geom_ribbon() + ggtitle('geom_ribbon()')
