Hi Jens,

You can use the Visual Overview ‘path’ shape date and refer to parameters from the Booking application storing R,G,B code for each state :

M 0,0 L 0,100 100,100 100,0;[param:01-SRM Application,306];[param:01-SRM Application,306]

Alternatively, instead of referring to the Booking Application, you could use a [reservation:] placeholder to grab it directly from the booking property. However, you’ll need a regex to convert to R,G,B string into a #aarrggbb string required by the ‘path’ shape data
