Issue: Is not staking

Having problems with the stacking on the graph panel, what I want is the 2 values tacked and identified differently, this is my table:

If I changed to graph:

SELECT DISTINCT CONCAT("WW",week(T.created_on)) as metric,X.SLAEXP as value,Y.SLAMET as value,Unix_timestamp(now()) as time_sec

If I change the ‘as value to value and value1’:

I really appreciate your help on this!

Please, help on this?
