<p><font face="monospace">I had exactly the same issue on a machine
that was previously upgraded from BackupPC 3 to 4 and displaying
double graphs on the dashboard.</font></p>
<p><font face="monospace">With the hint from the mail below, I found
the name of the bottom empty image I wanted to get rid of which
was in my case poolUsage4.png. The correct image is
poolUsage52.png on this instance. I then moved (to delete later)
the files :</font></p>
<p><font face="monospace">poolUsage4.png<br>
pool.rrd</font></p>
<p><font face="monospace">from /var/lib/backuppc/log (the dashboard
is now without graph) and then updated the graph with</font></p>
<p><font face="monospace">su - backuppc<br>
/usr/share/backuppc/bin/BackupPC_nightly 0 255<br>
/usr/share/backuppc/bin/BackupPC_rrdUpdate</font></p>
<p><font face="monospace">This re-creates</font></p>
<p><font face="monospace">poolUsage4.png<br>
poolUsage52.png<br>
poolUsage.rrd<br>
<br>
With the current timestamp. The dashboard now show correctly.
Maybe it would have been enough to only remove the pool.rrd
since the poolUsage4.png got recreated. In any case, dashboard
clean again. Hope this can help someone.</font></p>
