Thread: tread line help

Hi all,

I have a chart with 3 elements I want to show.

1) product
2) unknown number
3) date

example is in the attachment.

I want to be able to eliminate the high number of the unknowns (only show 0~3000) and added the treadline (30 days moving average) for each product.

Can someone help to take a look?
thanks in advance. sorry for the large data, no virus in the zip file.
