Homemade Chessboard

I was not sure if this was going to work..

Some day a friend of mine comes with an idea of making his own chessboard. In the same moment I knew I had to make my own too.

Bounding Box Filtered Grafana Panels (with Postgis)

If you can filter a panel by time, why not to use a bounding box?

Today at work I had to create some dynamic panels in Grafana for a project involving some geometry data in Postgresql (Postgis). Most of the data are polygons, with some meta data related to them.

Since we already use Mapserver with Postgresql for managing layers, it would be very natural to use the bounding box filtering, just like in WMS layers. This allow us to display statistics for some specific region of interest.
