Hi,
set in tool graphing something like:
/tool graphing
set store-every=5min
/tool graphing interface
add allow-address=0.0.0.0/0 disabled=no interface=all store-on-disk=yes
/tool graphing resource
add allow-address=0.0.0.0/0 disabled=no store-on-disk=yes

Then go to http://[ipaddress]/graphs/ and select your interface.
These graphs resets on reboot, so if you want better graph, collect data with "The Dude", or use something like cacti.
