This is using base, where I can control the x and y axis range, where exactly the line should be drawn.
plot(mtcars$mpg, mtcars$hp, ylim = c(0, 400), xlim = c(0, 50), axes = F, xlab = 'mpg', ylab = 'hp', pch = 16)
axis(side = 2, at = seq(100, 400, 100))
axis(side = 1, at = seq(10, 30, 10))
ggplot(data = mtcars, aes(x = mpg, y = hp))+geom_point()+
theme(panel.background = element_blank())+
scale_x_continuous(breaks = seq(10, 30, 10), limits = c(0, 50))+
scale_y_continuous(breaks = seq(100, 400, 100), limits = c(0, 400))
How do I add axis line exactly like base plot ? I have tried scale_y_continuous
and scale_x_continuous
but it always draws till the end of the plot.
To change the axis scales on a plot in base R Language, we can use the xlim() and ylim() functions. The xlim() and ylim() functions are convenience functions that set the limit of the x-axis and y-axis respectively.
Use scale_xx() functions It is also possible to use the functions scale_x_continuous() and scale_y_continuous() to change x and y axis limits, respectively.
You can get there using the ggthemes
package:
library(ggthemes)
ggplot(data = mtcars, aes(x = mpg, y = hp)) +
geom_point() +
geom_rangeframe(data = data.frame(mpg = c(10, 30), hp = c(100, 400))) +
theme_tufte() +
scale_x_continuous(breaks = seq(10, 30, 10), limits = c(0, 50))+
scale_y_continuous(breaks = seq(100, 400, 100), limits = c(0, 400))
You can also draw them manually, if you want:
ggplot(data = mtcars, aes(x = mpg, y = hp)) +
geom_point() +
geom_segment(
aes_all(c('x', 'y', 'xend', 'yend')),
data.frame(x = c(0, 10), xend = c(0, 30), y = c(100, 0), yend = c(400, 0))
) +
theme(panel.background = element_blank()) +
scale_x_continuous(breaks = seq(10, 30, 10), limits = c(0, 50), expand = c(0, 0))+
scale_y_continuous(breaks = seq(100, 400, 100), limits = c(0, 400), expand = c(0, 0))
