Uyezve, zviyero zveaxis zvinoshandiswa zvinofanira kunge zvakafanana kudzivirira pfungwa yekuchinja kwakanyanya kana kudiki zvakanyanya.
Chati yePai yeKuumbwa, ine Zvinyorwa
Machati emapai anowanzo shandiswa kuratidza zvikamu zvezvikamu zvine chekuita nechinhu chose, zvakaita sehuwandu hwevanhu zvichienderana nechitendero, basa, kana chiyero chemaruwa nemaguta. Kuona uku kuri nyore kunzwisisa, asi kune miganhu: kana paine zvikamu zvakawanda kana musiyano wezvikamu uri mudiki, zvinogona kuoma kuti muverengi aone saizi yezvidimbu.
Saka, machati emapai anofanira kushandiswa chete kana huwandu hwezvikamu huri hudiki (zvichida 3–5) uye musiyano wehuwandu hwacho wakajeka. Kune zviitiko zvine zvikamu zvakawanda, machati emabhara anowanzo shanda kupfuura machati emapai.
Piramidhi yeVanhu yeMagariro Ezera uye Bonde
Imwe yemifananidzo inonyanya kuonekwa mu demography ipiramidhi yevanhu. Girafu iyi inoratidza kugoverwa kwevanhu nezera ravo pa vertical axis, uye huwandu kana chikamu chevanhu pa horizontal axis, kazhinji zvakaparadzaniswa nevanhurume (kuruboshwe) nevakadzi (kurudyi).
Mapiramidhi ehuwandu hwevanhu anogona kuratidza mafambiro ekukura kwevanhu:
– Chimiro chakakura (hwaro hwakafara): huwandu hwakawanda hwevana vanoberekwa, huwandu hwevanhu vadiki vanotonga.
– Chimiro chisina kumira zvakanaka (chakanyatsoenzana): kuberekwa kunoderera, chimiro chayo chakasimba.
– Chimiro chakamanikana (hwaro hwakatetepa, pamusoro wakafara): huwandu hwevanhu vanokwegura, huwandu huri kuwedzera hwevakwegura.
Kubva papiramidhi, vaongorori vanogona kuwana mhedziso pamusoro pekudiwa kwemabasa everuzhinji: zvikoro nenzvimbo dzevana muvanhu vechidiki, kana mabasa ehutano nekuchengetedzwa kwevanhu muvanhu vakwegura.
Histogram yekuparadzira uye mapatani ekuparadzira
Mahistogram anoshandiswa kufungidzira kugoverwa kwedata renhamba rinoenderera mberi, senge kugoverwa kwezera revanhu (kwete nemapoka ezera anotsanangurwa), kugoverwa kwemari inowanikwa, kana kugoverwa kwehuwandu hwevanhu munzvimbo dzakasiyana. Nemahistogram, tinogona kuona kana data racho richiwanzoenderana, rakanamirwa kurudyi kana kuruboshwe, kana kuti riine peaks dzakawanda (multimodal).
Muzvidzidzo zvevanhu, mahistogram anobatsira kunzwisisa kusaenzana. Semuenzaniso, kana kupararira kwehuwandu hwevanhu kwakakanganiswa zvakanyanya, zvinoreva kuti kune huwandu hwevanhu vakawanda munzvimbo yakati, izvo zvinogona kukanganisa dzimba, kutakurwa, uye nharaunda.
Nhungamiro yeKuparadzira Hukama Pakati peZvinhu Zvinochinja
Mapoka ekuparadzanisa anobatsira zvikuru pakuongorora hukama huripo pakati pezvinhu zvakasiyana-siyana. Semuenzaniso, hukama huripo pakati pehuwandu hwevanhu nehuwandu hweurombo, kana pakati pemazinga edzidzo nehuwandu hwekuzvarwa. Nepoka yekuparadzanisa, tinogona kuona kana zvinhu zvinowanzova nehukama hwakanaka, husina kunaka, kana husina hukama.
Mapuratifomu ekuparadzanisa anogonawo kuwedzerwa nekuwedzera chati yemabubble kumiririra shanduko yechitatu, semuenzaniso, saizi yemabubble inomiririra huwandu hwevanhu vese vedunhu rega rega. Izvi zvinobatsira kuwedzera ongororo pasina kufanira kuratidza machati akawanda akasiyana.
Mepu dzeThematic (Choropleth) dzekugovera Nzvimbo
Kana ongororo ichisanganisira nzvimbo, magirafu echinyakare dzimwe nguva haana kukwana. Mamepu ane dingindira, kana kuti mamepu echoropleth, anoratidza data rine mavara akaenzana zvichienderana nenzvimbo. Semuenzaniso, mepu yehuwandu hwevanhu nedunhu, mepu yehuwandu hwevanhu vanononoka nedunhu, kana mepu yekufamba kwevanhu nedunhu.
Chakanakira mamepu ane dingindira nderekuti anogona kuratidza mapatani enzvimbo: ndeapi nzvimbo dzine vanhu vakawanda, dziri kukurumidza kukura mumaguta, kana kuti ndeapi nzvimbo dzinoda kupindira munharaunda. Zvisinei, mamepu ane dingindira anofanira kushandisa kupatsanura mavara kwakakodzera uye ngano dzakajeka kudzivirira kududzirwa zvisizvo.
Matanho Ekuongorora Ruzivo Rwevanhu Vachishandisa Maonero
Kuti magirafu nemadhayagiramu atsigire ongororo iyi zvechokwadi, matanho ekushanda akarongeka anodiwa:
1. Sarudza chinangwa chekuongorora: kana uchida kuenzanisa matunhu, kuona mafambiro enguva, kana kuongorora hukama huripo pakati pezvinhu zvinoshanduka.
2. Chenesa data: iva nechokwadi chekuti hapana zvikanganiso zve data risina chinhu, kudzokorora, kana kuisa.
3. Sarudza mufananidzo wakakodzera: gadzirisa rudzi rwedata (chikamu, nguva, kugoverwa, nzvimbo).
4. Kunyora mazita uye mamiriro ezvinhu: zita remusoro, chikamu, kwakabva data, uye nguva zvinofanira kunge zvakajeka.
5. Dudzira mhedzisiro: tsvaga maitiro, mafambiro, zvinhu zvisingawanzoitiki, uye zvinorehwa nemutemo.
6. Kuedza kuenderana: kuenzanisa nezvimwe zvinyorwa kana nguva dzakasiyana dzekusimbisa.
Nematanho aya, kuona zvinhu nenzira yekutarisa hakusi kungoshongedza mishumo chete, asi kunova chishandiso chekuongorora.
Mhedziso
Kuongorora ruzivo rwevanhu uchishandisa madhayagiramu nemagrafu inzira inoshanda yekunzwisisa mamiriro ehuwandu hwevanhu uye mafambiro avo. Mabhawa anorerutsa kuenzanisa kwezvikamu, magirafu emitsara anoratidza mafambiro enguva, mapiramidhi ehuwandu hwevanhu anotsanangura chimiro chezera nemurume nemukadzi, kugoverwa kwemamepu ehistogram, mapuratifomu akapararira anoongorora hukama huripo pakati pezvinhu zvakasiyana-siyana, uye mamepu ane dingindira anoratidza mapatani enzvimbo. Chinokosha pakubudirira chiri mukusarudza mifananidzo yakakodzera, kupa mharidzo yakajeka, uye kududzira kwakanyatsojeka. Nekuona kwakanaka, ruzivo rwehuwandu hwevanhu runogona kupa hwaro hwakasimba hwekuronga budiriro yakanangwa uye inoenderera mberi.
