Description Usage Arguments Aesthetics Computed variables Note Author(s) See Also Examples
This set of stats and geoms makes it possible to draw circles based on a
center point and a radius. In contrast to using
ggplot2::geom_point()
, the size of the circles are related to the
coordinate system and not to a separate scale. These functions are intended
for cartesian coordinate systems and will only produce a true circle if
ggplot2::coord_fixed()
is used.

mapping |
Set of aesthetic mappings created by |
data |
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 on the generated path per full circle. |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
|
inherit.aes |
If |
... |
other arguments passed on to |
stat |
The statistical transformation to use on the data for this layer, as a string. |
expand |
A numeric or unit vector of length one, specifying the expansion amount. Negative values will result in contraction instead. If the value is given as a numeric it will be understood as a proportion of the plot area width. |
radius |

geom_arc understand the following aesthetics (required aesthetics are in bold):
x0
y0
r
color
fill
size
linetype
alpha
lineend
The start coordinates for the segment
If the intend is to draw a bubble chart then use
ggplot2::geom_point()
and map a variable to the size scale
Thomas Lin Pedersen
geom_arc_bar()
for drawing arcs with fill
