For each continuous x value, geom_spct
displays a y interval.
geom_spct
is a special case of geom_area
, where the minimum of
the range is fixed to 0, but stacking is not enabled.
Usage
geom_spct(
mapping = NULL,
data = NULL,
stat = "identity",
position = "identity",
...,
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE
)
Arguments
- mapping
The aesthetic mapping, usually constructed with
aes
oraes_
. Only needs to be set at the layer level if you are overriding the plot defaults.- data
A data frame. If specified, overrides the default data frame defined at the top level of the plot.
- stat
The statistical transformation to use on the data for this layer, as a string.
- position
Position adjustment, either as a string, or the result of a call to a position adjustment function.
- ...
other arguments passed on to
layer
. This can include aesthetics whose values you want to set, not map. Seelayer
for more details.- na.rm
If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.
- show.legend
logical. Should this layer be included in the legends?
NA
, the default, includes if any aesthetics are mapped.FALSE
never includes, andTRUE
always includes.- inherit.aes
If
FALSE
, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g.borders
.
Details
An spectrum plot is the analog of a line plot (see geom_path
),
and can be used to show how y varies over the range of x. The difference is that
the area under the line is filled.

Examples
# ggplot() methods for spectral objects set a default mapping for x and y.
ggplot(sun.spct) + geom_spct()
