Changing Legend Items ggplot

Question

I am trying to create a chart, but I can't change the names of the legend items. My database is in Spanish, and I need the legend items to appear in English. Legend Items. Instead of "70 o más" I need "70+". I have already tried changing the value labels in the database and it is not working either.

This is the code for trying to change the value labels in the database

library(expss)

describe(Flow)


Flow = apply_labels(Flow,
                      mes = "Month",
                      ano= "Year", 
                      edad="Age", 
                    edad=c("70 or more" = "70 o Más S/E"), 

This is the code for the chart:

    chart<-ggplot()+
  geom_line(data=Flow %>%
            aes(x=date,
                color=edad), stat="count") +
  scale_x_date(date_minor_breaks = "1 month",
               date_labels = "%Y (%b)") +
  labs(color="Age")+
ggtitle("Number of Entrances, 2017-2021") 
ggplotly(chart)

I'd appreciate any help!

You can use scale_colour_gradient to set breaks, then change the labels.

library(tidyverse)

ggplot() +
  geom_line(data=mtcars,
              aes(x=cyl, y = mpg,
                  color=mpg)) +
  scale_colour_gradient(breaks = c(15, 20, 25, 30, 40),
                        labels = c("1+", "2+", "3+", "4+", "5+"))

Output
