log scale without transformation?

[jayoung]

hi there,

This is just a "wouldn't it be nice" request - I would love it if it were possible to plot graph-like tracks on a log-scaled y-axis, rather than actually transforming the data.

Is there a way to do it in Gviz? I could imagine transforming the data, then hacking into the y-axis labels to un-log them, but that seems like a pain.

See example plot I'll attach to show the kind of thing that would be nice. The code I used to make that is below, although that's less relevant.

thanks again,

Janet

library(tidyverse)
library(patchwork)

dat <- data.frame(x=c(1,2,3,4),
                  y=c(1,10,100,1000) )

p1 <- dat %>% 
    ggplot(aes(x=x, y=y)) +
    geom_col() +
    scale_y_log10() +
    labs(title="I like this y-axis")

p2 <- dat %>% 
    ggplot(aes(x=x, y=log10(y))) +
    geom_col()  +
    labs(title="better than this one")

p1 + p2
