Indlela yokwakha igrafu "kwiLizwi" usebenzisa ipredishithi?

Abo baqala ukuqhelana nolwazi olukhoyo lwe-text editor evela kwiMicrosoft, ndifuna ukuthetha ngokusebenza kwayo ngokunokwenzeka. ILizwi yinkqubo leyo, xa ifundwe ngokugqibeleleyo, nawuphi na umsebenzisi uyaqonda ukuba akukho mfuneko yokufaka isofthiwe esongeziweyo ukudala iintetho, iincwadana, iincwadana kunye nokuxazulula iingxaki zeemathematika ezinzima. Kubandakanywa umhleli wombhalo uxhotyiswe ngezixhobo, apho kulula ukuphendula umbuzo wendlela yokwakha igrafu. "KwiLizwi" ungasetha iiparameters zetshathi zaluphi na uhlobo. Kuphela abo abangayazi indlela yokuya kwithebhu efunekayo kwaye yintoni idatha yokwenza ngexesha lokwakha ayinakujamelana nemisebenzi enjalo.

Iigrafu kwiLizwi 2007

Umhleli wombhalo ovela kwiMicrosoft ngo-2007 uhluke kakhulu kwi-interface yayo yesofthiwe ngo-2003. Kodwa abo basetyenziselwa ukugqibela, kuya kuba lula ukujongana "neLizwi" yenguqu ephezulu. Inyaniso kukuba onke amamenyu kunye nemiyalelo yabaphuhlisi nje bazisa kwiithebhu, ezifanayo ziboniswa kwiinkqubo zecrowser. Kwaye "kwi-Vord-2007" kwakungekho mfuneko yokukhangela inketho efunekayo, ukuvula iwindow yehla-phantsi kwaye enye.

Ukuphendula umbuzo wendlela yokwakha imifanekiso kwi "Word", kufuneka kwakhona ukuya kwithebhu ethile. Abaphuhlisi baxhomekeke kubo kwinani elipheleleyo lemifanekiso, kodwa ukwenzela ukuba bangadideki, siya kubhala yonke into ngokulandelelana. Ngokomzekelo, sisombulula ingxaki yokuphanda umsebenzi olula.

Umzekelo womsebenzi

Cinga ukuba y = 2x-3. Emva koko ukwenzela ukwakha igrafu yomsebenzi, kubalulekile ukucacisa ezinye ixabiso le x. Sibaphatha ngokukhawuleza. Umzekelo, x = 1, x = 1.5, x = 2, x = 2.5. Kufanelekile ukukhankanya ukuba kumsebenzi ongezantsi kunamathuba amabini aneleyo, kodwa masithathe iine, kuba ngokubalulekile kubakho ukuxazulula ingxaki ekuchazeni umgaqo wendlela yokwakha igrafu "kwiLizwi". Emva koko sixazulula i-equation ngokufaka endaweni ekhethiweyo yexabiso x. Ngenxa yoko, y iya kuba -1, 0, 1, 2 (ngokulandelanayo).

Ukukhetha uhlobo lwegrafu

Emva kokusebenzisa umhleli wesicatshulwa, uye kwi-"Faka" ithebhu. Le yilapho imenyu yomzobo ikhona. Emva kokucofa kwi icon ehambelana nayo, iwindow ephumayo iya kuvela kwisikrini. Ibonisa iintlobo ezahlukeneyo zemifanekiso. Umsebenzisi kufuneka akhethe umgca ngegama elithi "Igrafu" kwaye nqakraza imouse kwi-"Kulungile" ibhokisi lokukhangela.

Ukwakha

Ithemplate iya kuboniswa kwiphepha. Njengomthetho, iqulethe imida emine eneengcongolo kunye neendlela ezimbini. Akunzima ukuqagela ukuba ixabiso elincinci liyi x, i-yile y y. Imigca ekhethiweyo kwisisombululo kunye nokwakhiwa kuya kutshintshwa enye, kodwa yinyaniso.

Xa umsebenzisi evuma ngokuhlukileyo okukhethiweyo kwegrafu, iwindi yeprogram iya kwahlulwa ibe ngamacandelo amabini. Ngakwesobunxele yiphepha elithi "Vorda", ngakwesokudla yi-Excel. I-spreadsheet sele iqulethe idatha ecacisa indawo yeemitha ezichazwe yiprogram. Ukuze uphendule umbuzo wendlela yokwenza igrafu kwiLizwi kumzekelo onikeziweyo, umsebenzisi ufuna ukutshintsha ixabiso lemiqolo (amagama abo akwiphepha eliphezulu le-spreadsheet), kunye neendidi. Endaweni yazo, kufuneka ufake ixabiso le x. Iikholamu ezimbini zeemigangatho kufuneka zisuswe, kwaye iimpawu ezifunyenweyo y kufuneka zingeniswe kwiixabiso eziseleyo. I-spreadsheet ithatha ifom elandelayo:

Njengoko umsebenzisi utshintsha idatha, umfanekiso wesigrafu uya kutshintsha kwakhona. Imigca emibini eyongezelelweyo iya kutshabalala, kwaye inxalenye esele iya kuthatha isimo esifanelekileyo.

Amanyathelo okugqibela "kwiLizwi"

Impendulo yombuzo wendlela yokwakha igrafu "kwiLizwi" ifunyenwe ngokuqhelekileyo. Kodwa kukho enye ingongoma. Inyaniso kukuba ekunene kwitshati ziimpawu zendlela eyenziwe kunye neyekude. Babizwa ngokuba "Row 1", "Row 2", "Row 3". Ukuchofoza kwidrafti kwindawo ezimbini zokugqibela, umsebenzisi unokuzicima ngokulula kunye neCandelo lokuCima. Isimboli eseleyo kufuneka siqeshwe kwiselfayile yespredishithi, endaweni yegama elithi "Row 1" ngokubhalwe "у = 2х-3".

Ukuthinta kokugqibela kwi-Excel

Emva kokuba umsebenzisi ususe iimpawu ezingadingekile kwindawo yetshathi, kufuneka asuse idatha eyongezelelweyo kwi-spreadsheet. Ukwenza oku, vele utshintshe uludwe lweedatha yedata ngokukhupha ikhoneni elingezantsi lasekunene lefomathi kwiimilinganiselo ezifunekayo.

Emva koko, igama y = 2x-3 liya kuboniswa phezulu kwidrafti. Kule nto, ukucwangcisa "kwiLizwi" kunokuqwalaselwa ngokupheleleyo.

Ezinye iinkalo

Umzekelo ukhankanywe yimpendulo kumbuzo wendlela yokwenza igrafu "kwiLizwi" ngomsebenzi olula. Kodwa yintoni enhle malunga nalo mhleli wombhalo, ngoko kukusebenza okuningi. Idatha engenayo ingasetyenziswa ngaphandle kwemigudu, kunye neefowuni ezimbini ze mouse, kwezinye iindidi zemifanekiso. Umsebenzisi ufuna kuphela ukungena kwindawo enye "Faka" ithebhu kwaye ukhethe nawuphi na uhlobo loboniso lweedatha yemifanekiso kwimenyu ehlile. Umhleli wombhalo uza kutshintsha uhlobo lwetshathi ngexesha elinye.

Isiphelo

Indlela yokudweba igrafu kwiLizwi? Lo msebenzi uyinto elula, kodwa ngaba ufanelekile ukuba ukusebenza komhleli wombhalo kusemhlabeni jikelele ukuba kukuvumela ukuba wenze umgca ngokuchaneka ukuya kwi-millimeter, emva kokufaka idatha kwi-spreadsheet? Ndicinga ukuba impendulo apha icacile.
