I have the following line charts for two different years ( by color).
I would like to Analyze if there is a significant difference or not between them.
?what options do I have in Tableau?
(I'm looking in the Analytics)
Please find my thought of adding a bar to show the difference between two lines as reference, below is the result.
Hope this could give you some ideas.
thank you (helpful)...
and I'm thinking I need to use R/Python to do ARIMA, etc. analysis?
