[rrd-users] Graphing two separate graphs from a DB

Similar to MRTG, I would like to have a graph for 24 hour and a separate
graph for 1 week.
I am pinging a host and graphing the latency.
I have an RRD called host-latency-db.rrd
I had two RRAs set up with 24 hours and 7 days but it is my understanding
the graph tool picks either/or depending on the data. I dont believe I can
graph off each RRA
Simply put, I want to ping a host, store the data and graph 2 separate
graphs with 24 hours and 7 days without having to ping it twice.
The only way I can thing to do this is after my get_data() command that
pings it, I run the following command
$rrdtool update host-latency_db.rrd --template pl:rtt N:$RETURN_DATA
I am assuming I will need two databases to store the information, 1 for a
day and 1 for an hour.
Then on my create graph script, I will have to have two rrdtool graph
calls, one on each DB, and create two separate graphs.
I was hoping there is a cleaner way or if I need two DBs and two graph
