"{solved} Problem in visualization of weighting"

Hi .. i know we can get a Graph for weighting but my problem is i have so many attributes and i just need attributes which weights are more than .5
so for doing this i used select by weight then used data to weight operators ....but THE big problem is when i use it ....data to weight,weights all remaining attributes 1 ! which is not correct ..what should i do?

Second question: which operators are good  or can be used for visualization...i already know that decision trees provide an excellent visual model....my job needs good graphs and model which are not so hard to explain yet they are attractive too
Danke schon
