Hi @Ken237 ,

May I ask if this is the expected output you are looking for? Based on your description, I calculated the averages for May-July and August-October separately and displayed the visuals on a line chart.

Please create a new Measure, and drag the new Measure to the Y-axis.

Measure2 =

SWITCH(

    TRUE (),

    SELECTEDVALUE ( 'Tabelle2'[Month] ) IN { "May", "June", "July" },

        CALCULATE (

            AVERAGE ( 'Tabelle2'[Resolution Time] ),

            'Tabelle2'[Month] IN { "May", "June", "July" },

            ALL('Tabelle2'[Month],'Tabelle2'[Index])

        )

        ,

    SELECTEDVALUE ( 'Tabelle2'[Month] ) IN { "August", "September", "October" },

        CALCULATE (

            AVERAGE ( 'Tabelle2'[Resolution Time] ),

            'Tabelle2'[Month] IN { "August", "September", "October" },

            ALL('Tabelle2'[Month],'Tabelle2'[Index])

        )

)

If this doesn’t work, could you please share some sample data without sensitive information and expected output.
