VAR _current_date = 'Table'[GRN Date]
VAR _end_point = EOMONTH(_current_date, -1)
VAR _start_point = EOMONTH(_current_date, -4) + 1
VAR _min_date_total = MIN('Table'[GRN Date])
VAR _result =

    Anonymous we are not dealing here with best practice stuff, but, as we created the column before you can create this measure to use as the line value:

    Average of Previous 3 Full Months Measure Dependant on Coloumn =
    AVERAGE('Table '[Average of Previous 3 Full Months Calculated Column])

Anonymous in your photo is that a data table and you need a calculated column or that is a visual table and you want to add a measure? If it's a visual what is the measure you have there for Lead Time (Days)?

        Hi SpartaBI , sincerrely apologise to interrupt you again. 
        I have face another difficulties that is similar to this question. However, in the current case, I would like to created visual table and add a measure. For example, based on the visual below, the light blue color bar can be refer to the average of the lead times (which i can just drag the column into the visual and click calculate average); the main problem that I face, is that how am i able to show the average lead time of the previous 3 month in the line value, for instance, the line chart of april should show 19  ,may is 22 , june is 15. Thanks you so much for your assistance
