Question: I want order the variable in Y axis based on the number of "Zero". Other than, what if I have 20 or more variable?
my data is simple and show in the fig:
I use ggplot2 to draw that, here is my code:
ggplot(data, aes(year, factor(name))) +
geom_tile(aes(fill =value),colour = "white") +
scale_fill_distiller(palette="Spectral",name="value") +
coord_fixed(ratio=1)+
scale_x_continuous(expand = c(0,0))+
scale_x_continuous(expand=c(0,0),
breaks=seq(1990, 2022, by=1)) +
theme_bw()
run the code:
dput(data) can show all the structure of data. The information display here:
structure(list(year = c(1998, 1999, 2000, 2001, 2002, 2003, 2004,
2005, 2006, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006,
1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006), name = structure(c(2L,

"a"), class = "factor"), value = c(0, 0, 0, 0.346651040983634,
