Opacity density layer on map

[LolaCottin]

Hello !

I have some uses with the density layer on Qlik Sense. I want the same opacity for all circle but different colors. I set opacity at 1 in the colors tab yet I have this :

(my current map)

Therefore, my legend doesn't have any opacity parameter.

(color legend on my current map)

I thinks is the weight of my point that create some opacity... How do I keep my measure without create transparency ?

(map without "weight by" field)

Something like this but with colors according to my measure (going from 0 to 2.37k) and not the count of points. 

Thank you in advance.
