works as expected

Hi everyone, Hi Hadley,

I am a heavy user of coord_equal() in ggplot2 since most of my data is spatial, on x,y coordinates. Everything works. However by enforcing an aspect ratio of 1 for the plotting region, coord_equal() usually wastes a lot of space if the region of interest is not a perfect square.

For example:

x=runif(10) a=data.frame(x=x*3,y=x) ggplot(data=a, aes(x=x,y=y)) + geom_point() + coord_equal()produces a square plotting region while all the data is constrained in an horizontally extended rectangle. I would expect the coordinates to stay equal but the plot to be extended so that it fills as much as the plotting region as possible. It does not appear to be currently doable. Is it a limitation of ggplot? of the underlying grids graphics? Is there a workaround this?

Thanks in advance for your help.

PS:

x=runif(10) qplot(x*3, x) + coord_equal()

produces some very strange scales. this looks like a bug to me. especially since:

foo=x qplot(foo*3, foo) + coord_equal()

works as expected

PPS: I tried

ggplot(data=a, aes(x=x,y=y)) + geom_point() + coord_equal() +
scale_y_continuous(limits=c(0,1))

which has no effect. but the side effect of enforcing the square
domain is that:

ggplot(data=a, aes(x=x,y=y)) + geom_point() + coord_equal() +
scale_y_continuous(limits=c(0,0.3))

has no effect either (i would expect to see only the points <0.3)
