r - Can't reference 'data' from within ggplot2 -


i object df not found when attempting this:

df <- data.frame(durationbin = 1:250, effort = 31:280)  ggplot(df, aes(x = durationbin, y = effort, fill = ..count../sum(df$durationbin == x))) +  stat_bin2d()

what i'm trying have density plot, except instead of density, "the percentage of points in column." (that is, points in column 100%, each column)

does know how this?
