Highlight Maximum Deviation

[jitpbi]

Hi,

On a line chart visual, "actual sales" and "target sales" are on Y-axis and "date" is on X-axis . On the secondary Y-axis, showing the "difference" (actual and target sales).

I have to highlight the highest "difference" ( with different colour/marker) on the chart.

Please help me out to achieve this.

Thanks

First create a difference column between actual and target sales:

Diff= 
VAR a = [actual sales]-[target sales]
Return 
VALUE(RIGHT(a,LEN(a)- IFERROR(FIND("-",a),0)))

Then flag the highest difference with measure:

Measure = IF(SUM('Table'[Diff])=CALCULATE(MAX([Diff]),ALL('Table')),1,0)

Try like

FormatMeasure = 
VAR MaxAmount = CALCULATE(MAXX(VALUES('Table'[Difference]),[Sales Amount]),ALL('Table'[Region]))
VAR LineAmonut = [Actual]
RETURN 
SWITCH (
    TRUE(),
    LineAmonut = MaxAmount, "GREEN",
    LineAmonut = MinAmount, "RED"
)

@jitpbi , I doubt conditional format work with more than one measure.

You can create two-measure highest and lowest difference and plot them with a marker .
