Description Usage Arguments Aesthetics Computed variables Author(s) Examples
A diagonal is a bezier curve where the control points are moved
perpendicularly towards the center in either the x or y direction a fixed
amount. The versions provided here calculates horizontal diagonals meaning
that the x coordinate is moved to achieve the control point. The
geom_diagonal()
and stat_diagonal()
functions are simply helpers that
takes care of calculating the position of the control points and then
forwards the actual bezier calculations to geom_bezier()
.

The data to be displayed in this layer. There are three options: If A A |
geom |
The geometric object to use display the data |
position |
Position adjustment, either as a string, or the result of a call to a position adjustment function. |
n |
The number of points to create for each segment |
strength |
The proportion to move the control point along the x-axis towards the other end of the bezier curve |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
