The code I used is as follows::

date_manip %>% na.omit() %>% ggplot(aes(x=Dia_week), group=1) + geom_bar(aes(x=Weekday)) + ggtitle("Travel by day of the week") + theme_clean()

Thank you,

Wil

First you can sort the data by day of the week:

date_manip$Dia_semana <- ordered(date_manip$Dia_semana, levels=c("domingo", "segunda-feira", "terça-feira", "quarta-feira", "quinta-feira", "sexta-feira", "sábado"))

And then the chart:

date_manip %>% na.omit() %>% ggplot(aes(x=Dia_semana), group=1) + geom_bar(aes(x=Dia_semana)) + ggtitle("Viagens por dia da semana") + theme_clean()

  • Maravilha @Josiane Souza! It worked super well. Thank you so much for sharing your knowledge! :-)

Hello, just change the data used in the X-axis to factor.

Below is a possible resolution:

date_manip %>% na.omit() %>% mutate(Dia_semana, levels = c("segunda-feira","terça-feira","quarta-feira","quinta-feria","sexta-feira","sábado","domingo")) %>% ggplot(aes(x=Dia_semana), group=1) + geom_bar(aes(x=Dia_semana)) + ggtitle("Viagens por dia da semana") + theme_clean()

  • Hello @hamers! Your solution is also good. It helped me a lot! Thank you
