Small multiples Parametric ON/OFF

[lucadelicio]

Goodmorning everybody,

i need to do a porting from another BI system.
I need to create a chart and line visual with the switch on/off option on the small multiples.

This is the chart when the Small multiple is ON

 and this is the result that i need when the small multiple is OFF

I try to create a parameter field to put into the filter ON/OFF:

PAR Country = {

    ("ON", NAMEOF('kpi-EV'[COUNTRY]), 0)

    ,("OFF", BLANK(), 1)

}
but it works just only for the ON and get error for the OFF option.

Have you got some ideas?
Thank you everybody

After many hours of works i resolved immediately after publish the post -.-''

This is the correct way to create the parameter fileds for switch OFF/ON the Small multiples!

PAR Country = {

    ("ON", NAMEOF('kpi-EV'[COUNTRY]), 0)

    ,("OFF", TRUE(), 1)

}

Thank you anyway!
