How to properly put lables on a faceted pie chart in ggplot?-CodePudding

So i have data like this:

tag  team   count    pct
E       A      12   1.00
E       B       5    .50
E       C       1    .20
I       B       5    .50
I       C       4    .80

I want to make a faceted pie chart with this data but I cannot get the text labels to appear in appropriate positions on the plot....what am I doing wrong here...


ggplot(data, aes(x = factor(1), y = pct, fill = tag))  
  geom_bar(stat = "identity", width = 1)  
  coord_polar("y", start=0)  
  theme_void()  # remove background, grid, numeric labels
  facet_wrap(~team) 
  geom_text(aes(label = sprintf("%1.2f%%", 100*pct)))

CodePudding user response：

You are on the right track!

Minor adjustments:

ggplot(df, aes(x = factor(1), y = pct, fill = tag))  
    geom_bar(stat = "identity", width = 1)  
    coord_polar("y", start=0)  
    theme_void()  # remove background, grid, numeric labels
    facet_wrap(~team) 
    geom_text(aes(label = sprintf("%1.2f%%", 100*pct)),position = position_stack(vjust = 0.5))   
    coord_polar(theta = 'y')

Need to include position= position_stack(vjust = 0.5) and coord_polar(theta = 'y')
