geom_abline does not work

[Daniel Lincke]

Hi all,

did anybody ever use geom_abline? It always draws a vertical line trough
zero ... thats not what it is inteded to do, right?

I treide the following versions:

geom_abline()
geom_abline(intercept=1,slope=2)
geom_abline(aes(intercept=1,slope=2))
geom_abline(intercept=1)

result is always the same.

Why?

Thanks.

Can you give us a reproducible example? It should draw a line that intersects y at specified height when x = 0 and with a certain slope. You can code this manually as you did in the second example or map it to a variable(s) as you did in the third example.

Can  you give us an example of what you're experiencing and perhaps what you're trying to achieve?

Cheers,

Roman

Here's a reproducible example:

library(ggplot2)
DF <- data.frame(x = rnorm(10), y = rnorm(10))

ggplot(DF, aes(x = x, y = y)) + geom_point() +
geom_abline(intercept = -0.5, slope = 0.7, color = "blue") +
geom_hline(yintercept = 0, linetype = "dotted") +
geom_vline(xintercept = 0, linetype = "dotted")

This works on my system:

It's more helpful to provide an example with data and code that
illustrates your problem than to claim "it doesn't work". Session
info such as that provided above can also be informative, so please
include that as well.
