Cacti has a nice feature. When you click on some of the graphs you can see separated graphs per main averages (Hourly - 1 minute average, Dialy - 5 minutes average, Weekly - 30 minutes average, Daily, Monthly - 2 hour average, Yearly - 1 day average).

I find this useful and for Zabbix seems we need to set separated items and separated graphs to get these averages... Plus that we need to messup the graph list with different versions of graphs based on average. Cacti approach is much better.
