Add linear line on on chart from right to left

[KarenFingerhut]

Morning all

I have posted this question i the past and it was solved but for some reason it has now stopped working and I can't (for the life of me) figure out how to fix it. Below is the link to my original question

Solved: Add a Linear line from top left to bottom right in... - Microsoft Fabric Community

I'm using the following Dax statement

IF (

    MAX ( 'Views Change Requests'[closed_at_value].[Date]) = MAXX ( ALLSELECTED( 'Views Change Requests'[closed_at_value].[Date]), 'Views Change Requests'[closed_at_value].[Date])

        || MIN ( 'Views Change Requests'[closed_at_value].[Date]) = MINX ( ALLSELECTED(  'Views Change Requests'[closed_at_value].[Date]), 'Views Change Requests'[closed_at_value].[Date]),

   COUNT('Views Change Requests'[number_value]))

And adding in a secondary line that relates to the above formula. Based on previously working I would expect it to work but no, all I am now getting it the below - as you can see the # Max Min line 2 is not appearing

What I would like to see is something like the below

Can someone please help me 😊

Thank you

Many thanks

Karen

Hi @KarenFingerhut 

Thanks for the reply from @DataNinja777 ,please allow me to provide another insight:

Maybe you can try this:

IF (
    MAX ( 'Views Change Requests'[closed_at_value] )
        = MAXX (
            ALLSELECTED ( 'Views Change Requests' ),
            'Views Change Requests'[closed_at_value]
        )
        || MIN ( 'Views Change Requests'[closed_at_value] )
            = MINX (
                ALLSELECTED ( 'Views Change Requests' ),
                'Views Change Requests'[closed_at_value]
            ),
    COUNT ( 'Views Change Requests'[number_value] )
)

If the above one can't help you, could you please provide more raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution.

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

Hi @KarenFingerhut 

Are you trying to add a linear regression line?  In that case, have you read the article below explains how to do it using dax functions?
