percentchangelog10 transform for the y scale.

Source: R/xgx_scale_y_percentchangelog10.R

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

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()
