How to automatically create the legend of a map?

[culea_catalin277313]

Hello everybody,
I have so much curiosity this time.

Below in the image we have 2 streets. I made a quantity legend for each of them.

Thank you for the enormous help you gave me.

 

I would somehow like to add all the polygon elements using a formula in the image below
then polyline type, respectively blocks (conventional signs).

As in the attached image.

 

But somehow the sum should be done only inside the contour of the Defpoints polyline, so that the quantities on each street come out.

 

Thank you in advance.
