Metric vis: '0' or '?' instead of "no results found"

[tbragin]

No data in the context of single-value widget may be a desired result. Take, for example, attached dashboard which displays data for Apache logs as a data source - lack of errors is a desired state, and ideally user would like to see "0" in that context.

This enhancement calls for this widget to display:

• "0" for count and unique count
• "?" for all other configurations, since they will be operating on an "unknown" quantity

I'd be in favor of showing empty plots instead of "?" for visualization types (other than count/unique count)

+1 I believe that is what the linked issue suggests: #3706

Please make an option to have ? or N/A (preferred) instead of an empty graph. I dont think they 2 are equivalent, an empty plot can be easily by one with 0 or very low values which is fundamentally different

👍 Just for the record, +1 here.

I have the same scenario: Wan't to track the number of errors - buf if its 0, No results found

[guybluebat]

+1 here as well

The count of an empty set is always defined and it is 0.

+1

PS An exception to this rule is of course the count of the set of all sets that do not contain themselves. That value is '?' indeed.
