Dynamic X Axis based on measure

My date set has these columns  -- these are about how much time one student need to finish his application

then each row is count 1  (These day / week / months are numeric so in date set it has a symbol of 'Σ (sigma)'

Application Day       XX Week   XX month etc..... Count

   14                            2                 0.5                     1

    30                          4.1                1                       1

.

.

.

Then my chart is simply line chart by Time to see when students tend to finish application 

X axis: Time (Day or week or month)

Y asis: sum of rows

So I want to setup a measureby using slicer (I used to do it for dyanmic measure, e.g. sum / divide / average X

Here is my half function:

Interval = SWITCH(TRUE(), MIN(para_Interval_Select[Interval ID])=1, min(applied_interval_days_reserve]), MIN(para_Interval_Select[Interval ID])=2, SUM(INTON_AppTimelines[applied_interval_weeks_reserve]))

THe problem for me is that I can't use sum or min or whateve calculation --- becasue they will return to single point -- as they aggregrate these days / weeks.

Is there a function for me to select all the value in the Measure? without calculation
