Pogwira ntchito yowonera deta yankhani, zidakhala zofunikira kukhala ndi nkhwangwa 4 zokhala ndi zilembo zabwino zonse.
Mofanana ndi ma graph ena m'nkhaniyo, ndinaganiza zogwiritsa ntchito gnuplot. Choyamba, ndinayang'ana pa webusaiti yovomerezeka, komwe kuli zitsanzo zambiri. Ndinasangalala kwambiri nditapeza yoyenera (Ndigwira ntchito ndi fayilo pang'ono ndipo idzakhala yokongola, ndinaganiza).
Ndinakopera kachidindo mwamsanga nβkuiyendetsa. Ndapeza cholakwika. Ndikulingalira. Zinapezeka kuti ndili ndi gnuplot yakale (Version 5.0 patchlevel 3 last modified 2016-02-21) ndipo sangachite zimenezo.
Podziwa za kusinthasintha kwa gnuplot, ndinayamba kuyang'ana pa World Wide Web ndipo ndinapeza zitsanzo zingapo zoyenera pa stackoverflow ( ΠΈ ) ndi github (). Iwo anakhala poyambira.
Kuphatikiza apo, kusintha kwanga ndi malamulo kunapangitsa kuti:

1) Pangani mizere 4 ziro - 2 yayikulu ndi 2 yowonjezera:
set xzeroaxis
set yzeroaxis
set x2zeroaxis
set y2zeroaxis
Mawu ochepa onena za zero mizere mkati . Opaleshoniyi imakulolani kuti mubweretse nkhwangwa pakati pa chithunzicho. Ndipo zowonjezera zimafunikira kuti muwonetse nkhupakupa zabwino pa iwo.
2) Konzani chiwonetsero cha nkhupakupa pa nkhwangwa:
max = 1.5 # ΠΠ»Ρ Π³ΠΈΠ±ΠΊΠΎΡΡΠΈ
min = -max
set xtics axis 0,.5,max in scale 0.5,0.25 mirror norotate autojustify offset 0.35
set ytics axis .5,.5,max in scale 0.5,0.25 mirror norotate autojustify
set x2tics axis .5,.5,max in scale 0.5,0.25 mirror norotate autojustify
set y2tics axis .5,.5,max in scale 0.5,0.25 mirror norotate autojustify
Ndi nkhupakupa pa nkhwangwa pali zosintha pang'ono.
axis - komwe nkhupakupa zidzapezeka, pa olamulira kapena (malire - pamalire).
Za axis x, yomwe imapita kumanja 0,.5,max. Nambala yoyamba ndi chiyambi cha kuwerengera, yachiwiri ndi sitepe, yachitatu ndi mapeto a kuwerengera. Kwa woyamba kuchokera 0, ndi kwa ena onse kuchokera 0.5, kuti ziro zisasokoneze chiyambi.
Kusakaniza ziro pa coordinate center.
Nthawi zonse *tics kukhazikitsidwa ngati 0,.5,max
Popanda offset 0.35 chifukwa xtics
kusintha scale 0.5,0.25 mirror amawonjezera notches ku axis. Ngati mumasewera ndi manambala, kukula kwake kudzasintha.
Ndikulowetsanso zosintha max, min, mothandizidwa ndi zomwe ndikuwongolera malire a ma ax a graph.
Zowonjezera pakukhazikitsa nkhupakupa zitha kupezeka muzolemba zomwe zili mugawoli .
3) Kupanga ma axis ranges:
set xrange [ min : max ]
set yrange [ min : max ]
set x2range [ max : min ]
set y2range [ max : min ]
Tiyenera kuzindikira apa kuti nkhwangwa za 2 zimayambira min kwa makulitsidwe ndi 2 nkhwangwa - ndi max kuchepa.
Zowonjezera mu gawoli .
4) Perekani mayina a nkhwangwa ndikuyika bwino:
set label "H_1" at 0, max center offset char 2, 0
set label "H_2" at max+0.1, 0 center offset char -1, 1
set label "H_3" at 0, min center offset char -2, 0
set label "H_4" at min, 0 center offset char 0, 1
5) Kupanga deta yolowera
Grafu iliyonse ili ndi mizati iwiri. Nambala ya mzere - nambala ya axis, mzere wachisanu kuti mutseke kuzungulira. Mzere wosamvetseka - coordinate x, ngakhale - y. Chifukwa chakuti mfundo zonse zili pa nkhwangwa, ndiye kuchokera awiriwo (x, y) imodzi nthawi zonse imakhala ziro.
Ngakhale nkhwangwa zonse 4 zili zabwino, zina zimasunthidwa molakwika kupita ku theka loyipa chifukwa zili pa nkhwangwa zazikulu. x ΠΈ y.
