Gantt Chart- code request for percentage completion line

Hi zakhtar , 

I find that the older version seems to use js  and css file instead of only json file, and when replace folder in new version's pbix, there is something wrong. I will discuss this with others and also will try the sample fom your link, I will inform you as soon as I get it.

Thanks for your understanding and support.
Best Regards,
Zoe Zhi
