I suggest you delete and then resubmit this LPT using the simple, precise, and correct rule:
"Fewer" is used with countable items, "less" is used with uncountable quantities.
In the UK, prescriptions are free to diabetics, so I'm a bit surprised you have a non-zero unit cost. Is your graph the cost to patients, or to the health service?

Reply to LPT - Don't know if it's less or fewer? 'Fewer' is a more precise word than "less". Say the sentence in your head, and try "fewer" first. Generally speaking, if that word fits, it is correct. by RPoliticsModsFU

Less sand, but fewer grains of sand.
Less stupid, but fewer idiots.
