Dear Reza

I think you missed this part of the documentation

"Finally, on the plot of weights, a horizontal reference line is drawn 
at 100/k, corresponding to the value for equal weights (in %) for all k 

The influential points marked with a different colour are, I think, 
those which are influential on any of the criteria outlined in the 
documentation and not necessarily influential with respect to the weights.
