Okulandelayo kuzokunikeza isisekelo esiqinile sokuqhubeka nokufunda izimiso ezimbili ezibalulekile zeshadi le-P & F: amazinga okusekela namazinga wokumelana. Kufanele ukhumbule ukuthi kokubili ukwesekwa nokumelana kukhonjiswa emigqeni evundlile nakuma-trendline amelwe ngama-engela angama-45-degree.

Amazinga Okusekela

Izinga lokusekela izinga lapho abatshalizimali nabahwebi ngokufanayo bakholelwa ukuthi amanani azoqala ukukhuphukela phezulu ngemuva kokushaya uphawu lokusekelwa. Bheka ama-O amathathu kusibonelo esingenhla ukuze ubone ukuthi kusho ukuthini lokhu. Umugqa ovundlile we-O’s yilokho okufunayo lapho ungena ngaphakathi ekuguqulweni kwethrendi kanye nokuphakama kokuqala.

Izinga Lokumelana

Umugqa ovundlile wama-X uphawula amazinga okumelana okudingeka ukuthi uwafune esifundweni seshadi le-P & F. Ucwaningo lwama-trendline luye lwabonisa ukuthi ukuhlukana ngamazinga okumelana ngokuvamile kwenzeka nge-gusto enkulu-okusho ukuthi, ngevolumu enkulu nangentengo yesitoko esanda ngokushesha.

Ngezansi

Amathrendi athatha isikhathi eside ukubuyela emuva, ngakho-ke abathengisi kufanele bakhumbule ukuthi ishadi le-P & F lenzelwe abatshalizimali besikhathi eside futhi alinalutho nakancane kumhwebi wesikhashana. Ngokusebenzisa amashadi wamaphoyinti nokubala ukukhomba izitayela zamanani esewonke, abatshalizimali bezobuchwepheshe bangathatha izikhundla ezinamathuba amakhulu okuzuza.
Lokhu nje ukubuka konke okuyisisekelo kwamashadi we-P & F. Incwadi enhle kunazo zonke ezake zabhalwa ngale ndaba ithi “Point and Figure Charting” kaThomas Dorsey. Le ncwadi iyimfuneko kubo bonke abafuna ukuqonda okunzulu ngale ndlela edumile yokushada. Kusukela kwethulwa amashadi we-P & F, bona
