xgx_scale_y_percentchangelog10

percentchangelog10 transform for the y scale.

Description

xgx_scale_y_percentchangelog10 and xgx_scale_x_percentchangelog10 are designed to be used with percent change (PCHG) from baseline data (on a scale of -1 to +Inf). Common examples include It is used when you have a wide range of data on a percent change scale, especially data close to -100

Usage

xgx_scale_y_percentchangelog10(
  breaks = NULL,
  minor_breaks = NULL,
  labels = NULL,
  accuracy = 1,
  n_breaks = 7,
  ...
)

xgx_scale_x_percentchangelog10(
  breaks = NULL,
  minor_breaks = NULL,
  labels = NULL,
  accuracy = 1,
  n_breaks = 7,
  ...
)

Arguments

`breaks`	if NULL, then default is to use a variant of 2^(labeling::extended(log2(PCHG + 1))) - 1, where PCHG represents the range of the data
`minor_breaks`	if NULL, then default is to use nicely spaced log10(PCHG + 1) minor breaks
`labels`	if NULL, then the default is to use scales::percent_format()
`accuracy`	accuracy to use with scales::percent_format(), if NULL, then the default is set to 1
`n_breaks`	number of desired breaks, if NULL, then the default is set to 7
`...`	other parameters passed to `scale_y_continuous`

Value

ggplot2 compatible scale object

Examples

dat1 <- data.frame(x = rnorm(100), PCHG = exp(rnorm(100)) - 1)

ggplot2::ggplot(dat1, ggplot2::aes(x = x, y = PCHG)) +
  ggplot2::geom_point() +
  xgx_theme() +
  xgx_scale_y_percentchangelog10()
