plotnine.geoms.geom_raster¶

class plotnine.geoms.geom_raster(mapping: Aes | None = None, data: DataLike | None = None, **kwargs: Any)[source]¶

Rasterized Rectangles specified using center points

Usage

geom_raster(mapping=None, data=None, stat='identity', position='identity',
            na_rm=False, inherit_aes=True, show_legend=None, raster=True,
            vjust=0.5, interpolation=None, hjust=0.5, filterrad=4.0, **kwargs)

Only the data and mapping can be positional, the rest must be keyword arguments. **kwargs can be aesthetics (or parameters) used by the stat.

Parameters:

mappingaes, optional

Aesthetic mappings created with aes(). If specified and inherit.aes=True, it is combined with the default mapping for the plot. You must supply mapping if there is no plot mapping.

Aesthetic	Default value
x
y
alpha	`1`
fill	`'#333333'`
group

The bold aesthetics are required.

datadataframe, optional

The data to be displayed in this layer. If None, the data from from the ggplot() call is used. If specified, it overrides the data from the ggplot() call.

statstr or stat, optional (default: stat_identity)

The statistical transformation to use on the data for this layer. If it is a string, it must be the registered and known to Plotnine.

positionstr or position, optional (default: position_identity)

Position adjustment. If it is a string, it must be registered and known to Plotnine.

na_rmbool, optional (default: False)

If False, removes missing values with a warning. If True silently removes missing values.

inherit_aesbool, optional (default: True)

If False, overrides the default aesthetics.

show_legendbool or dict, optional (default: None)

Whether this layer should be included in the legends. None the default, includes any aesthetics that are mapped. If a bool, False never includes and True always includes. A dict can be used to exclude specific aesthetis of the layer from showing in the legend. e.g show_legend={'color': False}, any other aesthetic are included by default.

rasterbool, optional (default: True)

If True, draw onto this layer a raster (bitmap) object even ifthe final image is in vector format.

hjustfloat (default: 0.5)

Horizontal justification for the rectangle at point x. Default is 0.5, which centers the rectangle horizontally. Must be in the range [0, 1].

vjustfloat (default: 0.5)

Vertical justification for the rectangle at point y Default is 0.5, which centers the rectangle vertically. Must be in the range [0, 1].

interpolationstr | None (default: None)

How to calculate values between the center points of adjacent rectangles. The default is None not to interpolate. Allowed values are: 'none', 'antialiased', 'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36', 'hanning', 'hamming', 'hermite', 'kaiser', 'quadric', 'catrom', 'gaussian', 'bessel', 'mitchell', 'sinc', 'lanczos', 'blackman'

filterradfloat, (default: 4.0)

The filter radius for filters that have a radius parameter, i.e. when interpolation is one of: 'sinc', 'lanczos' or 'blackman'. Must be a number greater than zero.
