The LDIR instruction is great here:

;Blacks Screen:
ld hl,plotsscreen     ;Start at plotsscreen
ld de,plotsscreen+1   ;Copies to the next byte
ld bc,767             ;768 (length of graph memory minus 1)
ld (hl),255           ;First byte of graph memory is all black
ldir                  ;The first byte is copied to the next 767 bytes!
