Calculated field with forecasting data on Tableau

Question

It is possible to put the forecasting data into a table, so you can work with them?

I need to show a number of how far our sales are from the tableau forecast, not just the graph.

UPDATE

I have two rows of data.

- PAST_DATA (2013 - 2014)
- CURRENT_DATA (2015)

I need to forecasting the past data and then compare the forecast data with the current data to calculate the difference. It this possible?

Answer 1

Go Worksheet > Copy > Crosstab and paste it into excel. You'll have the forecasting figures.

Or if you want to see it in a table in tableau, click Show Me and select text table.
