Change legend order

How can I change the order of the legends: .model appears first then level?

library(fpp3)

us_change %>%
  model(model1 = ARIMA(Consumption ~ PDQ(0,0,0)),
        model2 = ARIMA(Consumption ~ PDQ(1,0,0)),
        model3 = ARIMA(Consumption ~ PDQ(2,0,0))) %>% 
  forecast(h = 36) %>% 
  autoplot(us_change) +
  theme(legend.position ='top')

This should work:

library(fpp3)

us_change %>%
  model(model1 = ARIMA(Consumption ~ PDQ(0,0,0)),
        model2 = ARIMA(Consumption ~ PDQ(1,0,0)),
        model3 = ARIMA(Consumption ~ PDQ(2,0,0))) %>% 
  forecast(h = 36) %>% 
  autoplot(us_change) +
  guides(colour = guide_legend(order = 1), fill = guide_legend(order = 1)) +
  theme(legend.position ='top')

Thank you! Just what I wanted :smiley:
Could you explain how does order = 1 work?

The help documentation for that function can be found here.

order - positive integer less than 99 that specifies the order of this guide among multiple guides. This controls the order in which multiple guides are displayed, not the contents of the guide itself. If 0 (default), the order is determined by a secret algorithm.
