[rrd-users] no graph output?

[Karl Prinelle]

Hi list,
 
I've had some great initial success with my rrd efforts with data that
comes in at steady intervals (read: can use the values from the tutorial
to create the rrd!).  Now I need to create a rrd which will generally
get data every 10 mins.  I've worked out the parameters and can populate
the rrd and fetch from the rrd and all looks ok, but I just don't seem
to be able to get a graph out.
 
I've changed a few values & can see that the graph scale is changing
with my data so rrd does seem to know what data is in there, but it just
won't draw a line on the graph.  
 
Sorry this is such a newbie question, but I've read the
tutorial/manual/faq & think I'm obviously misunderstanding rather
fundamental!
 
Below are the rrd calls/config I'm making.
 
Sampling @ 10 mins, allowing a 20 min interval of "late" data.
2d 2h of10 min samples => 300 samples
12.5d + 2d 2h of 30 min samples => 700 samples
50d + 12.5d + 2d 2h of 2h samples => 775 samples
732d + 50d + 12.5d + 2d 2h of 1d samples => 800 samples
