- Rau overlay density plots , koj tuaj yeem ua cov hauv qab no:
- Hauv paus R cov duab, koj tuaj yeem siv cov kab () muaj nuj nqi . Tab sis nco ntsoov qhov txwv ntawm thawj zaj yog haum rau zaj tus thib ob.
- Piv txwv li: zaj ( ceev (mtcars$drat)) kab( ceev (mtcars$wt))
- Cov zis:
- Hauv ggplot 2 , koj tuaj yeem ua cov hauv qab no:
- Cov zis:
Tsis tas li ntawd, ua li cas koj overlay ib zajlus?
Rau overlay ntau cov phiaj xwm , koj tsim ib txheej rau txhua tus neeg zaj thaum koj cuam tshuam nrog Abaqus/CAE. Tom qab ntawd koj xaiv cov khaubncaws sab nraud povtseg los tso rau hauv qhov chaw saib tam sim no. Koj tuaj yeem tsim ntau txheej raws li koj xav tau; txhua txheej txheej tuaj yeem tshwm sim hauv tib qhov chaw saib.
Ib yam li ntawd, kuv yuav npaj ob kab hauv Excel li cas? Nyem qhov "Ntxig" tab, thiab tom qab ntawd xaiv daim ntawv qhia hom thiab sub-hom koj xav tsim. Piv txwv li, yog tias koj yog phiaj xwm Tshuag nqi dhau sijhawm, koj tuaj yeem siv a kab graph los yog tawg zaj . Cov ntaub ntawv no tau sau tias "Series 1." Txoj cai-nias qhov chaw seem ntawm daim ntawv, nyem "Xaiv cov ntaub ntawv," thiab tom qab ntawd nyem "Ntxiv."
Ua raws li qhov no, koj yuav ua li cas npaj qhov kev faib tawm qhov ntom ntom hauv R?
Qhov ntom ntom Txhawm rau siv lawv hauv R , nws yeej zoo ib yam li siv hist() muaj nuj nqi . Iterate los ntawm txhua kab, tab sis tsis yog ib tug histogram, xam ceev , tsim qhov khoob zaj , thiab tom qab ntawd kos cov duab. Ntau qhov puv cov phiaj xwm ceev . Koj tuaj yeem siv histograms thiab ceev kab ua ke.
Dab tsi yog pob Multiplot?
ntau ntau yog ib qho yooj yim los siv ua haujlwm los muab ntau daim duab rau tib nplooj ntawv siv R statistical software thiab ggplot2 plotting txoj kev. Cov haujlwm no yog los ntawm easyGgplot2 pob.

Dab tsi yog qhov ntom ntom hauv R?
Ib daim phiaj xwm ceev qhia qhov kev faib tawm ntawm tus lej sib txawv. Nyob rau hauv ggplot2, lub geom_density () muaj nuj nqi yuav siv sij hawm saib xyuas ntawm cov ntsiav ceev kwv yees thiab lub ntsiab lus soj ntsuam. Ib txoj haujlwm ntau hauv dataviz yog los sib piv cov kev faib tawm ntawm ntau pawg. Cov phiaj xwm ceev tshaj plaws uas koj tuaj yeem ua nrog ggplot2
Dab tsi yog qhov ntom ntom ntom ntom ntom ntom ntom?
Ib daim phiaj density yog ib qho piv txwv ntawm kev faib cov lej sib txawv. Nws yuav siv ib ntsiav ceev kwv yees los qhia qhov tshwm sim ceev muaj nuj nqi ntawm lub nce mus nce los (saib ntxiv). Nws yog ib tug smoothed version ntawm lub histogram thiab yog siv nyob rau hauv tib lub tswvyim
Dab tsi yog vim li cas ntawm qhov ntom ntom ntom?
Ntawm cov kua-cua sib cuam tshuam, qhov nro ntawm qhov chaw tshwm sim los ntawm kev nyiam ntawm cov kua molecules ntau dua rau ib leeg (vim kev sib koom ua ke) dua li cov molecules hauv huab cua (vim adhesion)
Dab tsi yog qhov txawv ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom nrog cov piv txwv?
Nws ua haujlwm nyob rau hauv ob qho tib si loj thiab me me thiab tsis yog raws li cov pej xeem ceev. Ceev dependent yam yog cov uas tswj cov kev loj hlob ntawm ib tug pej xeem nyob rau ntawm nws lub ceev thaum ceev ywj siab yam yog cov uas tswj pejxeem kev loj hlob yam tsis muaj nyob rau nws cov ceev
Lub raj mis ntom ntom siv li cas los nrhiav qhov ntom ntawm cov kua?
Qhov loj thiab qhov loj ntawm cov molecules nyob rau hauv cov kua thiab ze npaum li cas lawv tau ntim ua ke txiav txim siab qhov ntom ntawm cov kua. Ib yam li cov khoom, qhov ntom ntawm cov kua sib npaug ntawm cov kua faib los ntawm nws qhov ntim; D = m/v. Qhov ceev ntawm cov dej yog 1 gram ib cubic centimeter
