[pstricks] binomial-distribution

[Doris Wagner]

hi pstricks-list,

can anybody see, why the graph doesn't look like it should in the first  
example (p>=0.5) but looks ok in the second (p<0.5)???

i can guess that the problem is in closing some polygons...

I want to have a good-looking graph for p=0.5 where the problem also  
appears
