rsar possible RFE: ascii graphing of stats?

[ryran]

• This would probably require a flag to switch to an alternate mode where most of the traditional options are ignored.
• Would probably only be able to graph consecutive time spans which might require implementing something like sar's -e and -s options.
• Might not be able to use traditional sar options to decide what to graph -- instead might need to do a limited subset of specific items, e.g. kbmemused, kbswpused, %idle, etc.
• Perhaps png-generation using gnuplot or something else could come down the line.
