Kungani iningi lamagrafu namashadi libukeka kabi?

Ukubona idatha iyithuluzi elinamandla lokudlulisa ulwazi oluyinkimbinkimbi ngendlela ekhangayo. Ubuchopho bethu bucubungula futhi bugcine ulwazi ngendlela ephumelela kakhudlwana, buthuthukisa umthelela wabo ngokubuka ngeso lengqondo. Kodwa ukubonwa kwedatha okungalungile kungenza umonakalo omkhulu kunokuhle. Isethulo esingalungile singanciphisa okuqukethwe kwedatha noma, okubi nakakhulu, siyihlanekezele ngokuphelele.

Yingakho ukubonwa okuhle kuncike ekwakhiweni okuhle. Akwanele ukuvele ukhethe uhlobo lweshadi olulungile. Udinga ukwethula ulwazi ngendlela eqondakala kalula nebukeka kalula, okuvumela ababukeli ukuthi benze umzamo owengeziwe omncane. Yiqiniso, akubona bonke abaklami abangochwepheshe ekubukeni idatha, futhi ngenxa yalesi sizathu, iningi lokuqukethwe okubukwayo esikubonayo, masibhekane nakho, akukhanyi. Nawa amaphutha angu-10 ongase ungene kuwo nezindlela ezilula zokuwalungisa.

1. Ukuphazamiseka ezigabeni zeshadi likaphayi

Amashadi ophayi aphakathi kokubonwayo okulula, kodwa avame ukugcwala ulwazi. Indawo yemikhakha kufanele ibe enembile (futhi inombolo yayo akufanele idlule emihlanu). Kutuswa ukusebenzisa elinye lamaphethini amabili eshadi likaphayi alandelayo, ngalinye elizodonsela ukunaka komfundi olwazini olubaluleke kakhulu.

Inketho 1: Misa umkhakha omkhulu kunawo wonke ukusuka endaweni yehora le-12 futhi uqhubeke ngendlela yewashi. Eyesibili ngobukhulu isuka ku-12 ezimpondweni ngendlela ephikisana newashi. Imikhakha esele ingatholakala ngezansi, ngendlela ephambene newashi.

Inketho 2: Misa umkhakha omkhulu kunawo wonke ukusuka endaweni yehora le-12 futhi uqhubeke ngendlela yewashi. Imikhakha esele iyilandela ngokwewashi ngohlelo oluyehlayo.

2. Ukusebenzisa imigqa engaqinile eshadini lomugqa

Amachashazi namadashi kuyadida. Kunalokho, sebenzisa imigqa eqinile ngemibala okulula ukuyihlukanisa komunye nomunye.

3. Hhayi ukwakheka kwedatha yemvelo

Ulwazi kufanele lwethulwe ngendlela enengqondo, ngokulandelana okunembile. Hlela izigaba ngama-alfabhethi, ngobukhulu (ukwenyuka noma ukwehla), noma ngolunye uhlelo oluqondakalayo.

4. Ukuqoqwa kwedatha

Qiniseka ukuthi ayikho idatha elahlekile noma efihliwe ngemuva kwemiphumela yedizayini. Isibonelo, ungasebenzisa ukubonisa ngale endaweni ukuze wenze isiqiniseko sokuthi umbukeli ubona lonke uchungechunge lwedatha.

5. Umsebenzi owengeziwe womfundi

Gcina idatha ilula ngangokunokwenzeka ngokusiza umfundi ngezinto ezinemifanekiso. Isibonelo, engeza i-trendline eshadini le-scatter ukuze ubonise amathrendi.

6. Inkohlakalo yedatha

Qiniseka ukuthi zonke izethulo zedatha zinembile. Isibonelo, izakhi zeshadi lebhamuza kufanele zihlotshaniswe ngendawo, hhayi ngobubanzi.

7. Ukusebenzisa imibala ehlukene ebalazweni lokushisa

Eminye imibala igqama kakhulu kuneminye, ingeza isisindo kudatha. Kunalokho, sebenzisa amathoni ahlukene ombala ofanayo ukuze ubonise ukushuba, noma usebenzise ububanzi be-spectrum phakathi kwemibala emibili efanayo.

8. Amakholomu azacile kakhulu noma aminyene kakhulu

Ufuna ukuvumela ubuhlakani bakho busebenze ngendlela engafanele lapho udala isethulo, kodwa khumbula ukuthi kuzoba lula kumbukeli ukuthi abone umdwebo ovumelanayo. Isikhala phakathi kwamakholomu e-histogram kufanele silingane nengxenye yobubanzi bekholomu.

9. Idatha kunzima ukuyiqhathanisa

Ukuqhathanisa kuyindlela elula yokubonisa umehluko, kodwa ngeke kusebenze uma umbukeli engakwazi ukukwenza kalula. Imininingwane kufanele yethulwe ngendlela yokuthi umfundi akwazi ukuyiqhathanisa kalula.

10. Ukusebenzisa amashadi e-3D

Zibukeka zizinhle, kodwa izimo ze-3D zingahlanekezela umbono, futhi ngenxa yalokho zihlanekezele idatha. Sebenza ngezimo ze-2D ukwethula ulwazi ngendlela efanele.
