I think -Noodles- is probably correct. When I see stage plots, it's typically 50/50 as to how they're drawn up. Sometimes its from the bands perspective so the drums are in the back (would be at the bottom on a piece of paper) with the amps while the sidefills/wedges/vocal mics are at the front (top of the paper). The other half of the time it's from the audience's perspective; completely opposite.
Sometime the live sound company I work for doesn't even get stage plots, just input lists and such.
