I have legends like this. How can I change the order of the legends to "0,
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19."?

When the numbers are converted to to factors they are made into characters
and sorted by that.

Easiest way is to make it a factor and supply the levels. Something like:

library(tidyverse)

my_data_frame %>%
mutate(label = factor(label, levels = 1:19) %>%
ggplot(., aes(x=x, y=y, colour = label) + geom_line()

Is this for R or Python?

That is R code. If you have code to share that would be helpful because I
donât knohave how youâre using ggplot within python.
