Ask HN: Software for Time Series Data Manipulation

2 points by J_tt ↗ HN
Looking for something that can provide a user interface for most of the following:

- Applying variable offsets to numerical time series data (can be constant, linear etc, defined in simple mathematical terms) - Logging these changes and adjustments made to data with comments

The data is stored in Postgres, but could be moved or manipulated elsewhere as needed.

I've scoured the net but had no luck, I think I'm phrasing my question wrong.

Suggestions or pointers in the right direction much appreciated.

I'm not entirely sure from your description if I'm understanding the problem right but maybe Annotations in Grafana/InfluxDB might be what you're looking for?

I'm having trouble defining exactly how to phrase what I'm after.

Basically it's for a large collection of sensors in the field which require data to be routinely manually validated and modified

Based on your comment, I assume you mean a GUI program for interactive exploration and manipulation, rather than a library?

This was posted on HN a few months ago and came to mind: https://github.com/facontidavide/PlotJuggler

In a past job, we used the commercial app nCode Glyphworks for graphical / interactive signal processing from field tests with hundreds of sensors.

I think eraDB is built for time series data but I don’t know what tool other than whatever it ships with is best for manipulating the data itself
