Timelion visualization is wrong

Describe the bug:
The data is as follows
2020-03-22 = 38 Unique Conversations
2020-03-23 = 952 Unique Conversations
In the Chart visualization, when the mouse moves over the "2020-03-22" vertical bar, all points on the bar display a value of 38. Similarly when the mouse moves over the "2020-03-23" vertical bar, all points on the bar display a value of 952

In the Timelion visualization, when the mouse moves over the "2020-03-22" vertical bar, it shows 0 (zero !!!) on the bar till it crosses 07:00 hrs (coincidentally I am 7 hours behind UTC), then it displays 38. Similarly when the mouse moves over the "2020-03-23" vertical bar, it displays 38 all the way till you cross 07:00 hrs , then it displays a value of 952

My TimeLion configuration is as follows
.es(index=customer,metric=cardinality:conversation_id,q=*,timefield=ts).label('UNIQUE CONVERSATIONS').bars(width=10)

Steps to reproduce:

1. Build a Timelion graph
2. Build a Visualization graph with identical data as 1. above
3. We see that the data displayed is not same on both graphs

Expected behavior:
Data displayed should be identical

@sanjaysubramanian, Now timelion is using elastic-charts. On new implementation this problem is gone.

I close this issue but feel free to re-open if you find it again.
