How to display the peak value and date on card

[powerbiguy_]

I've been trying to display the peak value and date based on a graph. In my sample, I want to display 432,769.65 and 30-Tue.

Hello @powerbiguy_ ,

I agress with @Ritaf1983 solution but if you want without clicking a point, then you should create measure as below depends on the maximum value card visual will update automatically. 

Here is the sample data that I considered:

Your calculated measure looks as below:

Card Measure = 
Var a = MAX('Table'[Sales])
Var b = LOOKUPVALUE('Table'[Date],'Table'[Sales],a)
Return
"Maximum Sales are: "&a& UNICHAR(10)&"On: "&b

Output looks as below:

I thought that @powerbiguy_  wanted value based on his hovering.
Now, I understand that he wants the maximum value and its date.

I made some measures.

Step 1: I read the same data file 3 times , names of those datasheets are 'Sheet1', 'Sheet1+1', 'Sheet1-1' each.

Step 2: I added an index column in the 1st table 'Sheet1'.

Step 3: I added an index column in the 2nd table 'Sheet1+1'.

Step 4: I added an index column in the 3rd table 'Sheet1-1'.

Step 5: I made 2 relationships.

Step 6: I made some columns in 1st table 'Sheet1'.

Step 7: I made a mesure.

M_Max Peak = MAX('Sheet1'[Peak Value])
