Difference between price of two products for same date

[Matthew999]

So I was wondering how I would calculate the difference in DAX between two products in my table for the same date so I can see how the price spread changes over time. So my table would look like this: 

Date	Product	Price
7/18/2019	Corn	100
7/18/2019	Sugar	50
7/17/2019	Corn	90
7/17/2019	Sugar	60

And I would like this kind of output: 

	Corn minus Sugar
7/18/2019	50
7/17/2019	30

Ideally I would also be changing the dates (so maybe only charting the spread evolution over last 6 months) so FILTER incorporation would be ideal. Thanks in advance for any insight on how I could do this!

Assuming you only have two products, try the below measure: 

Measure = CALCULATE(SUM('Table'[Price]),'Table'[Product]="Corn") - CALCULATE(SUM('Table'[Price]),'Table'[Product]="Sugar")

That works! While there are more than one product, I can just make different measures because each product actually has a lot of other attributes attached (the same product will actually have multiple attributes that I will need to differentiate by like vendor source). Now that I have the framework I will give it a shot. Thanks!
