How to add color code whenever exception comes down in line graph

Hi sabih786,

As I know, we  can't set conditional format for data colors when we have legend. so one workaround is that you could try to add id in filter, and use clustered column chart at first

 

Total Sales = SUM(chart[amount])
% Change = 
VAR CurrentSales = [Total Sales]
VAR CurrentMonth = MIN(chart[year])
VAR PreviousSales = 
CALCULATE(
    [Total Sales],
    FILTER(
        ALLSELECTED(chart),
       chart[year] = CurrentMonth - 1
    )
)
RETURN
DIVIDE((CurrentSales - PreviousSales),PreviousSales)

Then switch chart to line chart, you will get result like below

 

You could refer to Power BI - Line Markers with Conditional Formatting for details.
