Delete bad data from a field / channel | General | Forum

At present there is not a way to delete a single feed. One option is to download all the data and then delete the single point and then re write all the data, to the same channel or to a new channel. This may consume a lot of messages, depending how much data is in your channel.

You can filter the data in several ways on the chart, by setting a data max or min, or by using median or averaging. If the bad data point is not the first in a particular block of data, you may be able to filter it using the timescale setting as well. (for the chart, which I understand is not what you asked)

For input filter, the best way is to create a second channel for the filtered data. You can set a react to run on data insertion for the first field and then have the react trigger a MATLAB analysis that applies the filter and then writes the filtered data to the new channel.
Since you can have only one React on data insertion, it may be better to have the react trigger on a time control and then process a batch of data each time the analysis runs.
