Always read the manual first.

rrdgraph manual refers to rrdfetch which states:

"Out of context (i.e. right after the + or - sign) the meaning of m is 
guessed from the number it directly follows. Currently, if the number 
absolute value is below 6 it is assumed that m means months, otherwise it 
is treated as minutes. (e.g., -6m == -6 minutes, while +5m == +5 months) "
