+This branch is an attempt to migrate from ChartJS 2.9.4 to 4.4.4.
+
+Here is a list of what has been done :
+- Uprgaded the ChartJS zoom plugin library, and changed the corresponding options in the chart configuration. The previous version was not working with the version 4.4.4 of ChartJS
+- Installing the date library Luxon and its adpater for ChartJS. This is needed because since version 3.x, time axes need these libraries.
+- Renamed or moved all needed parameters in the ChartJS configuration.
+- Changed all `xAxes` and `yAxes` references to `x` and `y`.
+- Adapted `afterBuildTicks` callbacks with the new signature (only `axis` is given)
+
+Here is a list of what needs to be done :
+- Change the implementation of the callback located in `options.scales.x.ticks` at chart creation in the Chart class, so it considers that the label is a timestamp. Reference : https://www.chartjs.org/docs/latest/axes/labelling.html#creating-custom-tick-formats
