Hi Joe,
this patch might help:
diff --git a/lib/Smokeping.pm b/lib/Smokeping.pm
index 2d6e1e5..f9d162c 100644
--- a/lib/Smokeping.pm
+++ b/lib/Smokeping.pm
@@ -1156,7 +1156,8 @@ sub get_detail ($$$$;$){
$q->param('epoch_start',parse_datetime($q->param('start')));
$q->param('epoch_end',parse_datetime($q->param('end')));
- @tasks = (["Navigator Graph".$name, parse_datetime($q->param('start')),parse_datetime($q->param('end'))]);
+ my $title = $q->param('title') || ("Navigator Graph".$name);
+ @tasks = ([$title, parse_datetime($q->param('start')),parse_datetime($q->param('end'))]);
my ($graphret,$xs,$ys) = RRDs::graph
("dummy",
'--start', $tasks[0][1],
now you can specify the title as a cgi parameter
cheers

> The above is also fine for me and would be much simpler. The only problem with it is that I don't know if/how I could modify the graph title of the png file generated? Maybe there's some other url parameter I can pass? E.g. ?displaymode=a;start=2007-08-15%2015:31;end=now;target=Customers.ITIS.otoro;title=customer.abc (<-note added parameter).
