scale_edge_size

Edge size scales

Description

This set of scales defines new size scales for edge geoms equivalent to the ones already defined by ggplot2. See ggplot2::scale_size() for more information. The different geoms will know whether to use edge scales or the standard scales so it is not necessary to write edge_size in the call to the geom - just use size.

Usage

scale_edge_size_continuous(..., range = c(1, 6))

scale_edge_radius(..., range = c(1, 6))

scale_edge_size(..., range = c(1, 6))

scale_edge_size_discrete(..., range = c(2, 6))

scale_edge_size_area(..., max_size = 6)

scale_edge_size_manual(..., values)

scale_edge_size_identity(..., guide = "none")

Arguments

`...`	Arguments passed on to `continuous_scale` `minor_breaks` One of: `NULL` for no minor breaks `waiver()` for the default breaks (one minor break between each major break) A numeric vector of positions A function that given the limits returns a vector of minor breaks. `oob` One of: Function that handles limits outside of the scale limits (out of bounds). The default (`scales::censor()`) replaces out of bounds values with `NA`. `scales::squish()` for squishing out of bounds values into range. `scales::squish_infinite()` for squishing infinite values into range. `na.value` Missing values will be replaced with this value. `expand` For position scales, a vector of range expansion constants used to add some padding around the data to ensure that they are placed some distance away from the axes. Use the convenience function `expansion()` to generate the values for the `expand` argument. The defaults are to expand the scale by 5% on each side for continuous variables, and by 0.6 units on each side for discrete variables. `position` For position scales, The position of the axis. `left` or `right` for y axes, `top` or `bottom` for x axes. `super` The super class to use for the constructed scale
`range`	a numeric vector of length 2 that specifies the minimum and maximum size of the plotting symbol after transformation.
`max_size`	Size of largest points.
`values`	a set of aesthetic values to map data values to. The values will be matched in order (usually alphabetical) with the limits of the scale, or with `breaks` if provided. If this is a named vector, then the values will be matched based on the names instead. Data values that don't match will be given `na.value`.
`guide`	A function used to create a guide or its name. See `guides()` for more information.

Value

A ggproto object inheriting from Scale

Note

In ggplot2 size conflates both line width and point size into one scale. In ggraph there is also a width scale (scale_edge_width()) that is used for linewidth. As edges are often represented by lines the width scale is the most common.
