LINESTX with slicer

[Ethanhunt123]

Hello, 

I am trying to calculate trends using slope and intercept 

I am using the following DAX, which is functioning well. However, the issue arises when I have a slicer on the order date. I want the dataset for the query below to also get filtered for that date range when a user applies a start and end date filter on the order date slicer

Revenue trend = VAR line =

LINESTX (
ALL('Sales order line fact'[Order date] ),
[Total revenue trend],
'Sales order line fact'[Order date]
)
VAR slope = SELECTCOLUMNS ( line, [Slope1] )
VAR intercept = SELECTCOLUMNS ( line, [Intercept] )
VAR x = SELECTEDVALUE ( 'Sales order line fact'[Order date] )
VAR y = x * slope + intercept
RETURN y

I was doing something incorrectly. Your solution worked perfectly. Thank you so much!  🙂

@Ethanhunt123 Hi! Try with:

Revenue trend =
VAR line =
LINESTX (
ALLSELECTED('Sales order line fact'[Order date]), -- This respects the slicer
[Total revenue trend],
'Sales order line fact'[Order date]
)
VAR slope = SELECTCOLUMNS(line, [Slope1])
VAR intercept = SELECTCOLUMNS(line, [Intercept])
VAR x = SELECTEDVALUE('Sales order line fact'[Order date])
VAR y = x * slope + intercept
RETURN y

I have tried this but I don't think so this is working see below 

Data without the filter on date 

Data with the filter on the date  - From Jan 1 till Sept

Values are the same as above. My assumption is if I am changing dataset then values should also get change

@Ethanhunt123 Can you share the pbix?
