Box and Whisker with two different filters

Hi. 

I am a beginner with Power BI. I would like your help. 

I need to build a box and whisker on one chart with one which have a value with filter and one without filter in order to compare a sample with all the samples of his category. 

When I say category which means I set up filter to get box and whisker per quarter / year  and his characteristic.

But guess my question I don't know how to do it.  😕 

I am wondering if we can add another chart on the box and whisker but I don't know how to do it ? 

On the chart can we set up a specific filtre on one champs and and do not apply for the rest of them ?

Can we add two values on one box and whisker chart ? 

Thank you for your help in advance
