SummaryBy default, the graphs on the Exinda appliance are of a time range of 1 hour. They can be changed and modified to see more historical data.
OverviewBy default, monitoring on the Exinda defaults to the last hour. This range can be changed to monitor a lot of different ranges, including custom ranges.
ResolutionFor graphs that have been updated in v7.0 (Hosts, Subnets, Applications, Application Groups, Virtual Circuits), to change the time range of the graph, find the drop down box in the upper right hand corner of the page. It will say "Show Data For: " and then the drop down, which will allow you to view whatever range you wish.
For graphs that have not been updated in v7.0 (the rest; most of them look like pie charts), to change the time range of the graph, there's a dropdown box in the upper left corner which specifies the range of the time shown on the graph. Other than the location, the behaviour is exactly the same as v7.0, as are the range options.
