Gauge otel meter in Time Series

Grafana Dashboards
1

Hello,
Grafana v10.4.3 (6e6fbf6a34)

I have two metrics, a gauge and a histogram coming from a .net openTelemetry application.
For the gauge I am getting how long a process is taking to execute [duration].
For the histogram I am observing the same process, I also have the duration of execution, but as it is a histogram is summing at new execution, and also counting number of executions.

I want to create a first simple dashboard with time series graph, plotting dots at each execution.
X-axis → timeline
Y-axis → duration of the execution.
it works in a certain way:

but the graph is plotting dots in between values (the last known value) what can be misleading.

and what I wanted is just one single dot per execution like:

is the gauge able to do that? is historgram maybe a better way to do it? getting a Delta of each execution?

Thank you very much,

Hi, is your data coming in a fixed interval of time (e.g. one minute). Also what’s your datasource (prometheus)?
If data is coming in fixed intervals, you can change the min interval (query options right next to datasource picker) to e.g. 1m

Thanks Dawiddebowski,
Indeed was the minimal interval of the dashboard that I need to change it was set to 15s, and my data is update at a minimum interval of 2min.
The datasource is Prometheus.

Ok, so setting min interval should work for you.
