... )
>>> table = session.read_pandas(df, table_name="Sales")
>>> cube = session.create_cube(table)
>>> l, m = cube.levels, cube.measures
>>> l["Date"].order == tt.NaturalOrder()
True
>>> cube.query(m["Quantity.SUM"], levels=[l["Date"]])
           Quantity.SUM
Date

2021-05-20           18
>>> l["Date"].order = tt.NaturalOrder(ascending=False)
