Hi, I am trying to annotate a plot with specific coordinantes, but I am not sure how to have the coordinantes displayed with brackets around them, and how to create an arrow, from the line to the annotation, so that the curve can be seen.

I am creating 10 plots like this, so I was also wondering if there was a way to automatically create arrows pointing in the correct direction to display the curve and the annotation.

Here is what I have done so far:-

A = [0,0.0590000000000000; 1,0.0608180621083432; 2,0.0615879573422760; 3,0.0603386593147987; 4,0.0598305894162876; 5,0.0598623273619486; 6,0.0584945748794018; 7,0.0577702151590919; 8,0.0605129150799025; 9,0.0620048213373498; 10,0.0605393857529640; 11,0.0577228309148774; 12,0.0545269901805093; 13,0.0565073063213107; 14,0.0588962692968848; 15,0.0646554192002185; 16,0.0653529156588946; 17,0.0640673165727952; 18,0.0624340511194904; 19,0.0631543194996316; 20,0.0629452706226184; 21,0.0646757622166786; 22,0.0647175708496279; 23,0.0656249289159351; 24,0.0658196162947984; 25,0.0655795574615578; 26,0.0631977170251018; 27,0.0609979983473740; 28,0.0629218306380116; 29,0.0610501667442434; 30,0.0585487582819609; 31,0.0580821579803593; 32,0.0562292159538292; 33,0.0572340748081928; 34,0.0562691703206619; 35,0.0575612158992794; 36,0.0583245385835296; 37,0.0588496200538721; 38,0.0572538716856298; 39,0.0566640164178741; 40,0.0551814025803676; 41,0.0587963688120286; 42,0.0579968315568868; 43,0.0536895112169952; 44,0.0551626051371020; 45,0.0540816350078450; 46,0.0547008772575487; 47,0.0541332759920487; 48,0.0530038170579354; 49,0.0494052496047877; 50,0.0495345840243639; 51,0.0484584597544044; 52,0.0460596033130027; 53,0.0474563474278678; 54,0.0444466067730615; 55,0.0429326641254798; 56,0.0451957674464573; 57,0.0427474722695884; 58,0.0402749977640400; 59,0.0367917420128257; 60,0.0326702213512802; 61,0.0322733521533463; 62,0.0297719248040272; 63,0.0290634547328883; 64,0.0253755104823977; 65,0.0242282988693209; 66,0.0220403843276571; 67,0.0141681138079521; 68,0.0138603809990626; 69,0.0166901467287308; 70,0.0177565201087299; 71,0.0178903024012334; 72,0.0183834476605889; 73,0.0172760072302439; 74,0.0188915053604907; 75,0.0170741035963220; 76,0.0149854280071022];
