Newbie question: have (looks like) valid rrd data, can't get the graph to appear in the status page

Tue Apr 29 23:04:16 CEST 2008

Can someone see what I'm missing?  I get a 'hobbit graph ncv:mysl'
link in the mysql status and trends pages, but no graph.

here's the data as it appears in the status page:
(ignore the low values for ThreadsCreated and OpenedTables, these
are values over the last sample interval - could probably have done this with
a DERIVE rrd dataType - I do the calcs in my collection script)
=====================================
QueriesPerSecAvg:5177
QueriesPerSec:1851
ThreadsConnected:396
ThreadsCreated:0
OpenFiles:19751
OpenTables:12500
OpenedTables:0
=====================================

here's my block from hobbitgraph.cfg:
