There is a high level routine called cursor and it
is very easy to use. Something like,
( $xc, $yc, $ch , $xref,$yref) =
$window->cursor( { XRef=>$xc,
YRef=>yc,
Type=>'CrossHair' } );
The help can be seen by typing
"help PDL::Graphics::PGPLOT::Window" on the
perldl command line. After that search for cursor
with "/cursor" and then "n".
Enjoy,
Xavier
