Could you attach your packaged workbook?
Sample data is enough to start investigation.
It's difficult to understand what we can do without seeing your data set.
Are ANALYTICS algorithms not guiding you to spot trends? If it is visualization, then using p-Value and 95% UCL and LCL are phenomenally useful to explain the data.
But I agree that sample data will be good start. You might have to create multiple workbooks as you subset and find underlying insights.
How can I attach the file? I dont see an attachment option here
Attached is the data, please let me know if you have nay problems opening it. We analyze the data on a rolling-12 month basis and I'd like to find out if its possible to add trending arrows that can compare either the current rolling-12 months to the previous one, or some data range selected the that same range the previous year. Please let me know if these or anything similar can be achieved and how.
