Sequential grey color scale for color aesthetic. The palette is computed using HSV (hue, saturation, value) color model.
start
- numeric
Gray value at low end of palette in range [0,1
]
end
- numeric
Gray value at high end of palette in range [0,1
]
name
- string
The name of the scale - used as the axis label or the legend title. If None, the default, the name of the scale
is taken from the first mapping used for that aesthetic.
breaks
- list of numbers
A numeric vector of positions (of ticks)
labels
- list of strings
A vector of labels (on ticks)
limits
- A pair of numbers specifying the data range for the scale.
Use null to refer to default min/max.
Missing values will be replaced with this value.
Guide to use for this scale.
It can either be a string ("colorbar", "legend") or a call to a guide function (guide_colorbar(), guide_legend())
specifying additional arguments.
"none" will hide the guide.
trans
- string
Name of built-in transformation ('identity', 'log10', 'reverse', 'sqrt').
