Stacked graph not showing on chart. R ggplot geom_area

Question

I am trying to show a stacked graph using an area chart. However, after i input the variables for x and y and the fill data, nothing shows on the graph.

ggplot()+
geom_area(data=provinces,aes(x=variable,y=value,fill=Province.State))

Province.State variable value
         Hubei 01.22.20   444
     Guangdong 01.22.20    26
         Henan 01.22.20     5
      Zhejiang 01.22.20    10
         Hunan 01.22.20     4
         Anhui 01.22.20     1
         Macau 01.27.20     6
         Tibet 01.27.20     0
         Hubei 01.28.20  3554
     Guangdong 01.28.20   207
         Henan 01.28.20   168
      Zhejiang 01.28.20   173
         Hunan 01.28.20   143
         Anhui 01.28.20   106
       Jiangxi 01.28.20   109

Answer 1

variable is not continuous; without transforming those strings into something numeric, it's a factor with three discrete values. Either use geom_bar(stat='identity'), to keep variable as a factor, or parse the dates:

ggplot(provinces,
  aes(x=as.Date(variable, format='%m.%d.%y'),
  y=value,
  fill=Province.State)) + geom_area()

(After parsing the data with:

provinces <- read.table(header=TRUE, text='Province.State variable value
         Hubei 01.22.20   444
     Guangdong 01.22.20    26
         Henan 01.22.20     5
      Zhejiang 01.22.20    10
         Hunan 01.22.20     4
         Anhui 01.22.20     1
         Macau 01.27.20     6
         Tibet 01.27.20     0
         Hubei 01.28.20  3554
     Guangdong 01.28.20   207
         Henan 01.28.20   168
      Zhejiang 01.28.20   173
         Hunan 01.28.20   143
         Anhui 01.28.20   106
       Jiangxi 01.28.20   109
')
