The derivate class dosn't behave like the base when i pass parameter to them

[drudox]

Indeed :

class DefaultPlot(BasePlot) :
   
    def __init__(self, figsize,**kwargs):
        self.params = kwargs
        print(kwargs)

give me {}

while

def __call__ (self,nrows,ncols,**kwargs):
       print(kwargs)
       self.setparams(kwargs)

give me {'scheme': 'vega'}

Well, easy to miss in a messy code. You pass

           self.setparams(kwargs)

where is double asterick?

in this poiunt is not necessary the **

I fixed the things and I solved .. thanks for the hint !!
