Combining two x-axes from same table to plot two measures on same graph

lbendlin I think I am missing something... 

Here is the structure of the reference table:

Here is one of the measures:

Not Met = 

Var TOT_STS = Calculate(COUNT('Student Language Levels'[Time to Exit Status]), 
'Student Language Levels'[Exit Status] <> "1 N/A" 
&& NOT(ISBLANK('Student Language Levels'[Time to Exit Status]))
)

Var TOT_MET =
Calculate(COUNT('Student Language Levels'[Time to Exit Status]), 
NOT('Student Language Levels'[Exit Status] IN {"1 N/A", "5 Not Yet"})
&& NOT(ISBLANK('Student Language Levels'[Time to Exit Status])),
FILTER(ALLSELECTED('Student Language Levels'), 'Student Language Levels'[Time to Exit Status] <= MAX('Student Language Levels'[Time to Exit Status]))
)

Var Percent_NOT_Met = Divide(TOT_STS-TOT_MET,TOT_STS)

RETURN Percent_NOT_Met

When I plot the measures against their respective "time" columns in the reference table, the respective plots work perfectly. But when I plot them against the new "days" table, I get a constant line which corresponds to the minimum value calculated by each measure. 

Do I simply add a filter to the two measures to set the selected(time to status) to Days[day]? Something like && SELECTEDVALUE('Student Language Levels'[Time to Exit Status]) = 'Days'[Days] ?

Thanks a lot!!
