Beside that this thread is from September 2013, it has been mentioned several times across the forum that the dashboard needs a revamp and provides only limited report functions. The developers are aware of that but there is no ETA when they'll revamp it as far as I know.So either wait, modify it on your own or try a report mod like the one from http://www.sudobash.net/category/osticket/Note that for the last 2 options there will be no more support since when you modify it you'll have to support it on your own since its not the official release anymore and might behave different etc.
