"Time series Disparity chart or YoY difference chart"
I 'm trying to depict the Max/MIN/Median differences of a time series data set. Please see below my data set and i wanted to depict the Year-over-year differences of a given sample.
I do have around 3k unique customerid's and wanted to get a sense of average differences of all these custid's with regards to there year-over-year sales trend. How do i show this in a good graphical way?
