Ordering climate data by months.

[munawar]

Hi!
I wanted to plot the yearly and seasonal temperature data from 1991 to 2020. However, the output graph showed months in disordered form (i.e. Apr, Aug, Dec etc) instead of the preferred Jan, Feb, March, and son on. Here is the figure:

Here is the code i ran:
ggplot(data=data_t,aes(x=Year,y=Temperature,group=Months))+
geom_boxplot()+facet_wrap(~Months)
Here is the part of the data for reference:
|Year|Months|Temperature|Country|spr|smr|aut|win|

Make the Months column a factor and set the order of its levels.

data_t$Months <- factor(data_t$Months, levels = c("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"))

Thanks a lot. That's a very accurate solution to my problem.
