This set of scales defines new size scales for edge labels in order to allow for separate sizing of edges and their labels.

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

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

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

scale_label_size_manual(..., values)

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



Arguments passed on to continuous_scale


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.


One of:


Missing values will be replaced with this value.


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.


For position scales, The position of the axis. left or right for y axes, top or bottom for x axes.


The super class to use for the constructed scale


a numeric vector of length 2 that specifies the minimum and maximum size of the plotting symbol after transformation.


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.


A function used to create a guide or its name. See guides() for more information.
