Combine coord_fixed() and coord_flip()?

[Ben Harrison]

I am trying to change the aspect ratio of a particular plot, and the only
way I've worked out to do this is with coord_fixed(). If there are other
ways, then this question might be redundant!

The plot describes the changes in a variable (GR) with depth.
Depth being independent, I place it in x, but as per custom, we plot depth
on vertical axis.
I also need depth to be increasing from top to bottom:

ggplot(data=logs, aes(x=DEPTH, y=GR)) + geom_line() +
scale_x_reverse() + coord_flip()

This is fine, but the aspect ratio is unfettered.

last_plot() + coord_fixed(ratio=1)

Has the desired effect, but resets the flip, so that depth is again on the
horizontal axis. Is there a way to combine the two? I haven't been able to
figure it out.

You can only use one coord_*() function on a given ggplot since it
changes the coordinate system after everything else has been done. To
change the aspect ratio, you can use the corresponding argument in the
theming system:

... + coord_flip() + theme(aspect.ratio = 1)

Untested in the absence of a reproducible example. If this doesn't
work, please provide one.

Thank you Dennis, that does work.

The docs at http://docs.ggplot2.org/current/theme.html do not mention this
at all.


Ben.
