- Cov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teeb tsa uas cov txiaj ntsig tau muab tso rau hauv qhov kev txiav txim ntawm qhov loj.

Tom qab ntawd, lo lus nug yog, kab lus siv yog dab tsi? A kab siv , kuj hu ua lub hauv paus kab , yog tus neeg siv-txhais ntsug ntsug lossis kab rov tav kab hauv daim duab. Koj tuaj yeem tso saib ib lossis ntau dua cov kab ntawv siv nyob rau hauv ib daim duab visualization, siv txawv kab hom. Cov kab ntawv siv muaj yog tias X lossis Y axis muaj qhov ntsuas.
Yog li ntawd, yuav ua li cas koj pom tus qauv sib txawv hauv tableau?
Txhawm rau nrhiav tus qauv sib txawv rau qhov ntsuas hauv tableau, nyem rau ntawm qhov ntsuas thiab xaiv tus qauv sib txawv:
- Nco tseg: Tus qauv sib txawv suav qhov kev sib cais lossis kev sib kis ntawm cov ntaub ntawv.
- Yuav ua li cas tableau xam tus qauv sib txawv?
- Nco tseg: Rau cov uas muaj Excel backkround, tableau siv Excel's STDEV.

Yuav ua li cas koj pom lub kaum sab xis nruab nrab muab qhov chaw thiab lub vojvoog ntawm ib lub sector?
Kev txiav txim siab Central Angle Los ntawm Sector Area (πr2) × (central angle in degrees ÷ 360 degrees) = sector area. Yog hais tias lub hauv paus lub kaum sab xis ntsuas nyob rau hauv radians, lub mis hloov mus ua: sector cheeb tsam = r2 × (central kaum hauv radians ÷ 2). (θ ÷ 360 degree) × πr2. (52.3 ÷ 100π) × 360. (52.3 ÷ 314) × 360
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
