Gantt - Hour granularity display

Open DigDash studio :
Create a gantt diagram with dates by an hour granularity, if possible at second granularity (unixtime will be good).

In the “Visualisation parameters” tab, click on “Advanced features”.
Add the feature “fixeScale” and et the value at 3 for the hour level.
