These scales allow more specific aesthetic mappings to be made when using geom_slabinterval()
and stats/geoms based on it (like eye plots).

Arguments passed to underlying scale or guide functions. E.g. scale_point_color_discrete
passes arguments to scale_color_discrete()
. See those functions for more details.
Names of aesthetics to set scales for.
Guide to use for legends for an aesthetic.
a numeric vector of length 2 that specifies the minimum and maximum size of the plotting symbol after transformation.
In discrete scales, should we show missing values?
When na.translate
is true, what value should be shown?
One of:
NULL
to use the default scale range
A numeric vector of length two providing limits of the scale.
Use NA
to refer to the existing minimum or maximum
A function that accepts the existing (automatic) limits and returns
new limits. Also accepts rlang lambda function
notation.
Note that setting limits on positional scales will remove data outside of the limits.
If the purpose is to zoom, use the limit argument in the coordinate system
(see coord_cartesian()
).
Should the shapes be solid, TRUE
, or hollow,
FALSE
?
A ggplot2::Scale representing one of the aesthetics used to target the appearance of specific parts of composite
ggdist
geoms. Can be added to a ggplot()
object.
The following additional scales / aesthetics are defined for use with geom_slabinterval()
and
related geoms:
scale_point_color_*
Point color
scale_point_fill_*
Point fill color
scale_point_alpha_*
Point alpha level / opacity
scale_point_size_*
Point size
scale_interval_color_*
Interval line color
scale_interval_alpha_*
Interval alpha level / opacity
scale_interval_linetype_*
Interval line type
scale_slab_color_*
Slab outline color
scale_slab_fill_*
Slab fill color
scale_slab_alpha_*
Slab alpha level / opacity. The default settings of
scale_slab_alpha_continuous
differ from scale_alpha_continuous()
and
are designed for gradient plots (e.g. stat_gradientinterval()
) by ensuring that
densities of 0 get mapped to 0 in the output.
scale_slab_linewidth_*
Slab outline line width
scale_slab_linetype_*
Slab outline line type
scale_slab_shape_*
Slab dot shape (for geom_dotsinterval()
)
See the corresponding scale documentation in ggplot for more information; e.g.
scale_color_discrete()
, scale_color_continuous()
, etc.
Other scale functions can be used with the aesthetics/scales defined here by using the aesthetics
argument to that scale function. For example, to use color brewer scales with the point_color
aesthetic:
scale_color_brewer(..., aesthetics = "point_color")
With continuous color scales, you may also need to provide a guide as the default guide does not work properly;
this is what guide_colorbar2
is for:
scale_color_distiller(..., guide = "colorbar2", aesthetics = "point_color")
These scales have been deprecated:
scale_interval_size_*
Use scale_linewidth_*
scale_slab_size_*
Slab scale_size_linewidth_*
Other ggplot2 scales: scale_color_discrete()
, scale_color_continuous()
, etc.
Other ggdist scales:
scale_colour_ramp
,
scale_side_mirrored()
,
scale_thickness
