Aloha all,
I love using ggplot. It took a while to get used to the grammar of
graphics, but it is starting to get easy now that I am thinking in a
more structured way.
A question. I'm making a wind rose that I'd like to be oriented with
due north straight up. I've discovered that the orientation is
sensitive to how north is represented. When north is represented as
0, the orientation looks to be shifted just a bit counter-clockwise,
perhaps 10 degrees. When north is represented as 360, the plot is
shifted clockwise, but past the point where north is straight up. How
to get north straight up?
I've read the book (very nice) and have skimmed through the
documentation without finding what I need. Any help much appreciated.
Here is the code from my Org-babel session:
#+begin_src R :session
library(ggplot2)
wind.data <- read.csv("pmrf_windrose_info_new.csv")
wind <- ggplot(wind.data, aes(x = degree, y = time, fill = wind))
wind.bar <- wind + geom_bar(stat = "identity")
wind.bar + coord_polar()
#+end_src
All the best,
Tom
