I am using the latitude and longitude of UK motorway junctions to plot the UK motorway network.
The approach I'm following is guided by
Using the Path Shelf for From - To Pattern Analysis | Tableau Software
I've been reasonable successful, but I'm caught up on one problem.
I've got as far as the M25 and the M1. But Tableau create a line between the end of the M1 and the start of the M25.
How could I avoid Tableau doing this?
