I created a yearly visualization, but the months on x-axis do not appear in order. I am lost about which function to order the months in ggplot.
You should have the dates either be a proper Date type variable, or if they must be 'text' then the dates should be ordered as factors.
If you would like more specific/concrete help. Please provide a reprex.
Yeah, but which function to use?
That depends on your data, which we don't know about.
