guide_edge_colourbar: Colourbar legend for edges

In ggraph: An Implementation of Grammar of Graphics for Graphs and Networks

Colourbar legend for edges

Description

This function is equivalent to ggplot2::guide_colourbar() but works for edge aesthetics.

Usage

guide_edge_colourbar(..., available_aes = c("edge_colour", "edge_fill"))

guide_edge_colorbar(..., available_aes = c("edge_colour", "edge_fill"))

Arguments

...

Arguments passed on to ggplot2::guide_colourbar title A character string or expression indicating a title of guide. If NULL, the title is not shown. By default (waiver()), the name of the scale object or the name specified in labs() is used for the title. theme A theme object to style the guide individually or differently from the plot's theme settings. The theme argument in the guide overrides, and is combined with, the plot's theme. nbin A numeric specifying the number of bins for drawing the colourbar. A smoother colourbar results from a larger value. display A string indicating a method to display the colourbar. Can be one of the following: "raster" to display as a bitmap image. "rectangles" to display as a series of rectangles. "gradient" to display as a linear gradient. Note that not all devices are able to render rasters and gradients. raster A logical. If TRUE then the colourbar is rendered as a raster object. If FALSE then the colourbar is rendered as a set of rectangles. Note that not all graphics devices are capable of rendering raster image. alpha A numeric between 0 and 1 setting the colour transparency of the bar. Use NA to preserve the alpha encoded in the colour itself (default). draw.ulim A logical specifying if the upper limit tick marks should be visible. draw.llim A logical specifying if the lower limit tick marks should be visible. position A character string indicating where the legend should be placed relative to the plot panels. direction A character string indicating the direction of the guide. One of "horizontal" or "vertical." reverse logical. If TRUE the colourbar is reversed. By default, the highest value is on the top and the lowest value is on the bottom order positive integer less than 99 that specifies the order of this guide among multiple guides. This controls the order in which multiple guides are displayed, not the contents of the guide itself. If 0 (default), the order is determined by a secret algorithm.

available_aes

A vector of character strings listing the aesthetics for which a colourbar can be drawn.

Value

A guide object
