Word cloud from Process Document

ElenaVet

Hi everybody!
How can I do a Wordcloud graph from che output of Process document with TF-IDF? The result is like this: 


I think about an aggragate to find the sum of the columns and a traspose, but when I try it shows me also the word "sum" before every word and it is not good! 
Can anyone help me, please?

You can [rename by replacement], so if you have attributes like sum(word1) you can use a regex to remove the sum() part.

like sum\((.*)\) replace with $1
