GOAL: apply curve logging to a time series of 10 data points.

CONTEXT: I am working on integrating curve-logging into the Fleet Management Blueprint, in order to do so I am retrieving data from the Kuksa.val databroker and then adapting them to be compliant for the curve logging to work properly.

EXPECTED OUTPUT: if the time series is greater than 3 points, the output should convey the same trend/shape/pattern with fewer points. From my perspective it is safe to assume that you would always have a returned reduced vector of at least 3 datapoints.

CURRENT OUTPUT: The current output is a vector with only one point.

For example, assuming a linear time series of 10 data points from 0.0 to 9.0 I would expect an output of the first point, the last and one in between (because it's linear). However, what I get as an output is only the last point.

Here you can see the output from the example you provide in the repo (scalar.rs). The only change is the data that was made linear for ease in debugging.

For instance, the real life example would equate to: a truck starts at 0 seconds at speed 0 and after 10 seconds of linear increment it arrives at 10mph. Before sending this information to our database we want to curve log it.

Sidenote: If you want access to my code, I will add you to the repo.
