Another way of doing this is to say:
$i = which ($y>5000);
points($x($i), $y($i));
If this doesn't work then you either need to 'use PDL::NiceSlice;' or
use the more-verbose
points($x->index($i), $y->index($i));

In other words, I want to plot only points whose coordinates fulfil a
certain condition. This is a feature I've used in sm.
