hmmm, I see a lot more breaking things now:

1. Why is the graph now reloading everytime we click on it?
2. It seems that the 'Direct Neighbor' column in the table is not updated

Okay the main issue is that I used the interval computed property in the ReportMixin.vue which under the hood listens for the changes of query date field. This works well for getting alarms from X time to Y time but this cause re-rendering of the data vizs when clicked because the dates is updated in the query address.

I handled the case of reloading the graph everytime as shown in the following video

From your last screenshot it seems to work as expected. Thanks!
