Sugestion: Allow Math operation in Graphs

[luyper]

It would be great if would be possible to make math operations when create graph itens. For example: We could include an item in graph that shows TotalMemory-FreeMemory (getting UsedMemory with result) or ProcessorUtilUser + ProcessorUtilSystem (getting total cpu usage). This are examples of itens that dont exist and could be showed in graphs with math operations.
