This works OK on my Mac - although some of the graph on the printout
got clipped off (missing x tick labels and a small portion of the
leftmost part of the graph (minimum x value on printout looks to be
about 1.4 instead of the value on the screen and what it should be of
1.0 )
So this appears to be specific to Linux (at least) -- wonder if there
is a different character on Linux to use instead of the ! -- Is there
anywhere in the Documentation Center that has platform specific
details?
