How to plot reverse (complementary) ecdf using ggplot?

Question

I currently use stat_ecdf to plot my cumulative frequency graph.

Here is the code I used

    cumu_plot <- ggplot(house_total_year, aes(download_speed, colour = ISP)) + 
                 stat_ecdf(size=1)

However I want the ecdf to be reversed(complementary ecdf). Any ideas of the easiest way to do this?

Cheers!

Answer 1

From the help page of stat_ecdf:

Computed variables

x

x in data

y

cumulative density corresponding x

So this works:

p <- ggplot(dataframe_with_column_Z, aes(x=Z))

p + geom_line(aes(y = 1 - ..y..), stat='ecdf')
