Splunk dashboard single value trendinterval time as dynamic

[splunkkid]

Hello,

I' m currently working on how to make dashboard with our Server's VM Count logs.

Our logs are being collected as daily basis, I'm trying to show the count trend using trellis by data center.

The command are like below.

host=[HOST] index=[INDEX] sourcetype=[SRC_TYPE] source=[SRC]
| timechart limit=0 span=1d sum(vm.count) as VM by center

If I make single value trellis viz with above command, I found the difference of VM count is only shown as daily basis. Like the pic attached.

I want to make trendinterval option value to dynamically change if I click time picker to change time range.

Like, If I change time range to Last 90days, then showing me the difference between today and 90days ago.

How could I make it so?

Thank you.

Here's an example that works for me:

index=_internal sourcetype=splunkd source=*/splunkd.log* earliest=-90d
| timechart limit=0 span=1d useother=f count by component

By default, it compares the two most recent values (today and yesterday). Is your "Compared to" option set correctly?
