Graph Question

We have a Table named Final Sheet with columns Date, Channel, Device, Country, UV, PDP UV, Catalog Page UV, Cart Additions, Checkouts, Orders. I want to create measures named as CVR = Orders/UV, UV to PDP = PDP UV/UV, UV to Catalog = Catalog Page UV/UV, P2C = Cart Additions/PDP UV, C2C = Checkouts/Cart Additions, C2O = Orders/Checkouts. Then I want to make 5 slicers one of Country, Second of Channel, Third of Device, fourth of Date and Fifth slicer containing all of the following columns UV, PDP UV, Catalog Page UV, Cart Additions, Checkouts, Orders, CVR, UV to PDP, UV to Catalog, P2C, C2C, C2O. With all these filters we want to create operate Graph which shows the trend of last 7 days with the selected dates.

We tried unpivot method by creating columns of CVR, UV to PDP, UV to Catalog, P2C, C2C, C2O but with this the graph started giving sum of CVR, UV to PDP, UV to Catalog, P2C, C2C, C2O. The average function also doesn't works for this as the average is not giving accurate data.

Please suggest how we can solve this.
