Data in the legend scatter

hello

i wanna know please how i can not include in the scatter option the data in the legend

becase when i use with this loop for example:

for i=1:boardSize %cicrle the soliders that will remove with white color
    for j=1:boardSize
        if Board(boardSize+1-i,j)==0
            scatter(j,i,700,Board(boardSize+1-i,j),'w','Marker','o','LineWidth',5)
        end
    end
end

it will add to my legend every circle data 1, 2 ,3 for any finding

how can i use only with my legend without any addings

I guess you should have a look on gscatter.
