Sparklines in matrix using switch

Hi SUMESHKUMAR22 

I mocked a simplified demo and made some testing. I found something interesting:

• when the SWITCH function returns any valid number (e.g. 100 or 0) as an alternate value, the sparklines can display correctly;
• when the SWITCH function returns blank value as the alternate value, it displays blank on all rows. 

I haven't fixed why this happens. It seems there is some invisible filtering within the context that we don't know. 

At the moment, at least as a workaround, you can modify the alternate value BLANK() into 0 to display the sparklines. And switch off Row subtotals in the matrix to hide the total row. You will get a result similar to below image.

Hope this would be helpful. 

Best Regards,

Hi SUMESHKUMAR22 
According to the filter the sparks show only last 7 days, you can get the desired result with 2 steps :
1. Add the calculated column to the date table :

last 7 days flag =

var maxD = CALCULATE(max('Time_Period'[Day]),all('Time_Period'))

var minD = maxD-6

var check = if('Time_Period'[Day]>=minD && 'Time_Period'[Day]<=maxD,1,0)

Return check

2. Use this column in your original DAX code :

Selected_KPI_Value_Sparkline =

VAR SelectedKPI = SELECTEDVALUE(KPI_Table[KPI Name])

VAR Last_7_Days = DATESINPERIOD(Time_Period[Day], MAX(Time_Period[Day]), -7, DAY)

VAR Click =

   CALCULATE(

       COUNTROWS('VBI Vaccines'),

       'VBI Vaccines'[EVENT_NAME] = "Click_Delivered",

       Last_7_Days

   )

VAR Conversion = COALESCE(

    CALCULATE(

        COUNT('VBI Vaccines'[EVENT_NAME]),

        'VBI Vaccines'[EVENT_NAME] IN { "click-through" , "view-through" },

        Last_7_Days

    ), 0)

VAR Impression =

   CALCULATE(

       COUNTROWS('VBI Vaccines'),

       'VBI Vaccines'[EVENT_NAME] = "Impression_Delivered",

       Last_7_Days

   )

VAR CTR = DIVIDE(Click, Impression, 0)

RETURN

if(SELECTEDVALUE(Time_Period[last 7 days flag])=1,   SWITCH(

       TRUE(),

       SelectedKPI = "Impressions", FORMAT(Impression, "0.00") * 1,

       SelectedKPI = "Clicks", FORMAT(Click, "0.00") * 1,

       SelectedKPI = "CTR %", FORMAT(CTR * 100, "0.00") * 1,

       SelectedKPI = "Conversion", FORMAT(Conversion, "0.00") * 1,

       0

   ),BLANK())

Result :

According to minimum/maximum labels, unfortunately, we don't have the functionality .
But you can use some workaround to show it after the spark like I did in the attached image :

Or use a tooltip from the measure itself :
