colored box under a line graph?

[Mark Knecht]

Hi,
I'm sorry. I was sure I read how to do this about a month ago and
thought Id saved the post but I cannot find it. I've Googled around
looking for it and cannot find it. Is there an example somewhere of
how to shade a portion of the background of a line plot? I.e. - On a 5
year plot where the events on the plot go through say the spring
quarter I might want to shade the background green, summer light red,
etc.

Thanks,
Mark

Hey Mark,

I've become a great fan of Hadley Wickham's ggplot2 over the last months. See pp 86-87 of his book for a cool example of what you want to do http://had.co.nz/ggplot2/book/

BTW, be sure to download the book's PDF as it will go away as soon as Springer's edition is out.

Mark,

Basically, you draw them with rect, probably with a transparent
color. See here for a detailed example:
