I'm trying to replicate the heat map with numbers from ggplot2 in ggvis. ggplot2 version is
library(ggplot2)
hec <- as.data.frame(xtabs(Freq ~ Hair + Eye, HairEyeColor))
ggplot(hec, aes(Hair, Eye)) +
geom_tile(aes(fill = Freq)) +
geom_text(aes(label = Freq),colour="white")
and it looks like that
My version in ggvis is
hec%>%
ggvis(~Hair, ~Eye, fill=~Freq)%>%
layer_rects(width = band(), height = band()) %>%
layer_text(text:=~Freq,fontSize := 20, fill:="white",baseline:="top",align:="center") %>%
scale_nominal("x", padding = 0, points = FALSE) %>%
scale_nominal("y", padding = 0, points = FALSE)
and the result is not perfect
I've tried to fix numbers align by manually adding margins, but this case is not resizeable.
Any ideas?
