Hello,
You are almost there.
With scale_x_continuous use argument limits.
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
scale_x_continuous(breaks = 1:6, labels = 1:6,
limits = c(1, 6))
And with xlim it's not a vector c(1, 6), it's each element on its own:
xlim(1, 6)
Or
lims(x = c(1, 6))
But with these two, the labels are not like you want them, they are 2 by 2.
Hope this helps,
Rui Barradas

I am sure I am doing something stupid but I can't see what. I am plotting data
and want the x axis labels to reflect the theoretical range of the x variable
which happens to be 1:6 but the observed values have range 2.6 to 5.9.
I thought xlim(c(1,6)) should have got me that quite simply but it doesn't. I
think this is a reproducible example of my failures (!)
library(tidyverse)
library(ggplot2)
x <- seq(2,5.8,.2)
list(x = x,
y = rnorm(length(x))) %>%
as_tibble() -> tibDat
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
xlim(c(1,6))
# x labels on plot are 2, 4 & 6
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
expand_limits(x = c(1,6))
# same
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
scale_x_continuous(breaks = 1:6, labels = 1:6)
# x labelled at 2:5 (why?!)
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
xlim(c(1,6)) +
coord_cartesian(clip = "off")
# back to 2, 4, 6
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
xlim(c(1,6)) +
coord_cartesian(expand = TRUE)
# same
### OK, getting desperately hopeful
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
xlim(c(0,6))
# x axis has 0, 2, 4 and 6 (surely inconsistent behaviour?)
ggplot(dat = tibDat,
aes(x = x, y = y)) +
geom_point() +
xlim(c(0.1,6))
# x axis has 0, 2, 4 and 6
Can anyone see the simple answer that is eluding me?!
TIA,
Chris
