Option to Filter bucket data when viewing it on the Dashboard

[georgevbsantiago]

The bucket data filter option to view in the widget (time series, tachometer, text...) would be important to omit noisy measurements.
The intention is that the user places the Filter parameters in the Widget and noisy measurements are not visualized in the widget (time series, tachometer, text...).
The Filter option is different from the "Transform" option.
If there are noisy measurements, the "Transform" option will be influenced.
The Filter option aims to exclude noisy measurements from the graph display and improve the "Transform" calculation.

It may be possible to implement the Filter in Influxdb, as stated in this part of the documentation:

KAUFMANS_ADAPTIVE_MOVING_AVERAGE()

Kaufman’s Adaptive Moving Average (KAMA) is a moving average designed to account for sample noise or volatility. KAMA will closely follow data points when the data swings are relatively small and noise is low. KAMA will adjust when the data swings widen and follow data from a greater distance. This trend-following indicator can be used to identify the overall trend, time turning points and filter data movements. Source

Hi @alvarolb

Is it feasible to implement a Filter option with Influxdb so that noisy data is not visualized in the widget graph when the source is the bucket?
It would be important for the functionality to be made available for the Time Series and for KPIs such as the Tachometer

[georgevbsantiago]

We need an approach (a filter option) that allows us to use algorithms and parameters that eliminate noisy measurements from the widget visualization (time series, tachometer...).
The Aggregation and Transformation option does not work for us, as noisy readings impact the value results.

Just a supplementary note.

A "noisy measurement" is not always bad.
In the case of distance sensors, a "noisy measurement" may indicate that there is an object close to the sensor that needs to be moved away from the sensor.
A "noisy measurement" can sometimes signal the need for some inversion in the context close to the sensor.
However, for most customers, they do not need to see this information on the chart. Seeing "noisy measurements" is of most interest to technicians operating the equipment. For the client (e.g. decision-making manager) he wants to see the graph without the "noisy measurements".
The technician, when viewing noisy measurements in other dashboards or analysis, will know that it is necessary to adjust or repair the sensor that generated the "noisy measurement".
