Why does it show on genetic algorithm plotting 'gaplotgenealogy not supported for this algorithm'

I used @gaplotgenealogy to see if I could find where each new Children comes from (Elite, Crossover, Mutation). But it shows on plotting 'gaplotgenealogy not supported for this algorithm'? I simply coded as opts = optimoptions('ga','PlotFcn',{@gaplotscores,@gaplotgenealogy,@gaplotstopping} Anyone has an idea why it shows words like that?

If you enter

help gaplotgenealogy

you see at the end of the help this statement:

    NOTE: This plot is only available after the GA has stopped and can not
    be used for nonlinear constrained problems.

So, do you have any nonlinear constraints?

Yea. I think the nonlinear constraints should be the problem. I guess what I can do is to just not use gaplotgenealogy in this case.
