ggplot flip and transform coordinate

Question

I want to transform the coordinate (not the scale/values) so that the y variable (flipped to x) is better spaced. I thought it would be coord_trans(y=\"log10\") or

Answer 1

OK so now that I understand your question, here's the answer in hopes it will help others.

First, the coord_* functions cannot be stacked - they override each other. So tthe way you are using it, coord_flip(...) overrides coord_trans(...) and you don't see any transformations.

To get log10 spacing with tick labels based on the linear spacing, with flipped coordinates, you can use the breaks=... argument to scale_*, as in:

ggplot(dat) +
  geom_point(aes(y=median, x=name)) +
  scale_y_log10(breaks=1000*(1:3)) +   # note use of breaks=...
  coord_flip() +
  theme_bw() +
  theme(
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(),
    panel.border = element_blank(),
    axis.line = element_line(color = 'black'),
    panel.background = element_blank(),
    axis.title.y = element_blank())
