Question #147716 on Graphite changed:

Status: Open => Answered
chrismd proposed the following answer:
Currently graphite will only show as far back as the retention of the
database files, so this means your whisper files must have only 30
minutes of retention. You can verify with the whisper-info.py command,
run it on the wsp files for the metrics you're viewing.
Keep in mind if you make changes to storage-schemas.conf, that only
affects wsp files when they get *created*. If you already had a wsp file
and want to changes its retention configuration, you have to either
delete it and let it get recreated with the new storage scheme, or
resize it using the whisper-resize.py script.
A newer branch I'm working on resolves this issue and shows the
requested interval always, which is less confusing. It also does away
with the fixed retention approach.
