Column Calculated using Slider Input



I am a new user of Power BI and am having an issue getting a visual to work.

The table below has fixed values for X and Y is calculated using the formula shown. Power BI 1.JPG


The Parameter[Value] is varied by a slider, shown below.

But changing the slider value does not change the table values. 

Is there a way to do this?

hi @adriankelly 

First, you should know that:

1. Calculation column/table not support dynamic changed based on filter or slicer.
2. Measure can be affected by filter/slicer, so you can use it to get dynamic summary result in a visual.


Second, for your case, you just could just create a simple measure as below:

Y = SUM('Table'[X]) - 'Parameter'[Value]


And then drag this measure into visual.


and here is sample pbix file, please try it.

Hi @v-lili6-msft,


Thanks for your response. 

The sample file contained what I was looking for. 

Coming from an excel background the DAX language and operation is a bit confusing .

Is the Y measure below storing the results in an array? 



hi  @adriankelly 

No, measure will calculate by it row context in a visual. It likes you define a function, then call it by row text in a visual.

Calculated columns are calculated at load and not affected by slicers and report interactions. You need a measure.


Y = 
VAR CurrentXValue = MAX('Table'[X])
VAR Result = CurrentXValue - [Selected Value]



You can see my PBIX file here

Calculated columns appear to be very Excel-like, but they are anything but, and should generally be avoided. There are times to use them, but it is rare. Getting data out of the source system, creating columns in Power Query, or DAX Measures are usually preferred to calculated columns. See these references:

@adriankelly seems like [Value] is a measure, you should be adding [Y] as a mesure. What actually you are trying to achieve? 

Read this for calculate column and measures.
