Chart line without aggregation in Kibana

I would like to create a chart line out of the following values:

But somehow I'm not able to get it working, Kibana is always aggregating the values, but I would like to have just one value for one time point:

Is this possible?

It's always going to be an aggregation, but you can change the interval of the buckets. By default this is set to Auto.

And why?

Let's say I want to display the power consumption of one device in watts over time, then the aggregation is not true..
