position_stack

position_stack(vjust=None, mode=None)

Adjust position by stacking overlapping objects on top of each other. Preferred for density-like geometries.

Parameters:

vjustfloat

Vertical adjustment for geoms that have a position (like points or lines), not a dimension (like bars or areas). Set to 0 to align with the bottom, 0.5 for the middle, and 1 for the top.

mode{‘groups’, ‘all’}, default=’groups’

If ‘groups’, objects inside one group are positioned as in position=’identity’, but each group is shifted to sum of heights of previous groups (where height of a group is a maximum of it’s y values). If ‘all’, each object will be shifted.

Returns:

FeatureSpec

Geom object position specification.

Notes

Adjust position by stacking overlapping objects on top of each other.
