Trend Line Chart without Grouping option

Dear Community,

I would to ask You for some support in area of Trend Line execution. I have a case that I would present trend line for defects only, with two statuses "closed" and "new".

I don't see any option how to add addional gropuing as in distribution graph or additional filter.

Is there any option to do that?

Right now i can present only defects with changes and new, what is not my aim.

Thank You!
