Carpet plot

Carpet plot panel plugin for grafana.

How to use

This panel receives data series and divides all the data into individual buckets. It groups the data first by day and then by a selected fragment of a day (hour / 15 minutes / minute). If there are multiple data points in a bucket (for example there were multiple series) it aggregates the points using a selected function (average, sum, count).

The data are displayed in a grid where each bucket is presented by corresponding color calculated from a selected color scheme.

Tested with InfluxDb data source.
