Plots to use G sharp in new composition (6)
I believe the answer is:
graphs
'plots' is the definition.
(graphing is a kind of plotting)
'g sharp in new composition' is the wordplay.
'in new composition' is an anagram indicator (I've seen this in other clues).
'sharp' with letters rearranged gives 'raphs'.
'g'+'raphs'='GRAPHS'
'to use' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for graphs that I've seen before include "Diagrams showing relationships between things" , "Diagrams that show ratios" , "Drawings with quantities ploted on axes" , "Diagrams with horizontal and vertical axes" , "Drawings showing relationships between things" .)
