From a data source on Google Cloud, with a table that contains 2 columns :

Month (DATE)

Cost (NUMERIC)

the query :

SELECT * FROM ( SELECT Month ,cost FROM MyTable ORDER BY 1 ASC )

My query does not allow me to display a time series dashboard, with the months on the abscissa and the costs on the ordinate.

How to do it ? What query should I make ?

Thanks for help, Didier
