[R] graphing help: line runs off top of graph

[Faheem Mitha]

Hi,

See the files at

http://bulldog.duhs.duke.edu/~faheem/R/

Usage is

$ Rscript memgraph.R meminfo.csv

Output is meminfo.pdf. As you can see, one of the lines (blue) runs off 
the top of the graph. Can anyone suggest a way to avoid this happening?

Please CC me on any reply. Thanks in advance.

                                                         Regards, Faheem.
