Display Data in Graph Panel for some Custom Range for time in X-Axis

I have a doubt, your global time filter is: 7 days and you just kept
Relative Time as 90m, then how it picked 11:50 to 13:10?

Because I took that screenshot at 13:12, and 90 minutes before that is 11:42.

You can see from the additional “graph space” before and after the first / last
labels on the X-axis that that’s the timescale the graph covers.

and what GMT time region we need to select?

I am not in GMT; I am in CET.

if possible, screenshot of your dashboard query might helpful.

Sorry, can’t manage that. I provision all panels using JSON, and since
Cannot create query - new Grafana installation I can’t view
anything useful in edit mode in the browser.

It still works fine in Grafana 5.4.5, but that looks completely different, so
isn’t helpful for you.

What I can share is the information from the Query Inspector, which tells me
that the query Grafana is submitting to my back-end data store is:

select RTT from stats where topic = ‘Calls’ and Dir=‘outbound’ and time >=
now() - 90m

So, what Grafana has done is to set $timeFilter to “time >= now() - 90m”

That’s the sort of things you can do manually if you want to create more
complex exceptions for individual panels.
