Hi,

I am trying to analyze some video play data. I have 4 primary columns :  
#1 Video Id  
#2 User Id  
#3 Video Watched (video watched in seconds)  
#4 Video Length (video length in seconds)

I am trying to create a vertical graph with x axis as completion rate bins (Ex : 0-10% completion, 11-20% completion etc.) for which I will have to create a new field 'video watched' divided by 'video length' and,

y axis as the count of videos.

Best!

Hello,

You can achieve this in a line chart, by creating a scripted field that does the division "video\_watched"/"video\_length" and then using that as a histogram with 0.1 intervals (which would equate to 10% intervals if using percentages in the field formatter)
