Using Firefox on Windows, I do not see tooltips in multigraphs.
The developer console shows various errors, one of them is:
'pos.y2 undefined in multigraph.php'
If I change line 78:
$("#y").text(pos.y2.toFixed(2));
to:
$("#y").text(pos.y.toFixed(2));
then tooltips work for me and the error message disappears.
BR, Jörg.
PS: nice side effect is that the 'zoom range' is now also working again in the usual orange colour.
Re: V8.0.2 - bug in multigraph.php prevents display of tooltips
Thanks Jorg, corrected.
