Thanks for the clarification. I thought if we had a go-ahead from them, then we could use it but I was clearly wrong. Moving to a different library should not be a problem but my only concern is it would push back the schedule by a few days. I am done with the initial charts using HighCharts.js, and migrating them might take some time, so please be patient. :)
Please compare libraries within boundaries set, to make a better
choice for this project.
I will look into the other libraries again and try to pick an alternative as soon as possible.
