Jumps in Line Layer

[RichB]

Hi all,

Can anyone tell me how to fix the jumping that occurs on my map? When the paths cross a particular longitude there is a "jumping" that occurs and the line wraps the long way around the map. I have applied a transformation to the negative points (adding 360) that someone mentioned here:  https://community.qlik.com/t5/Qlik-GeoAnalytics-Discussions/Line-Layer-Behavior-in-the-Pacific/td-p/...

however it appears that this simply changes where the jump occurs. Instead of occurring across the (-180, 180) longitude line (point 2) it occurs accross the (0, 360) line (point 3) as shown in the maps below. The maps show paths consisting of a few points placed at critical longitudes to show where the jump occurs. 

The points on the map are given by: 

SmallData:
load * inline
[assetid, latitude, longitude, messagetime
2, 46.7522781 , 163.0435627 , 2019-07-26 02:39:16
2, 47.8609425 , 174.934958 , 2019-07-26 02:39:17
2, 47.9432986 , -179.0895877 , 2019-07-26 02:39:17
2, 46.386769 , -161.746896 , 2019-07-26 02:39:18

3, 30.7522781 , 5 , 2019-07-26 02:39:16
3, 30.8609425 , 1 , 2019-07-26 02:39:17
3, 30.9432986 , -1 , 2019-07-26 02:39:17
3, 30.386769 , -5 , 2019-07-26 02:39:18

4, -15.7522781 , 95 , 2019-07-26 02:39:16
4, -15.8609425 , 91 , 2019-07-26 02:39:17
4, -15.9432986 , 89 , 2019-07-26 02:39:17
4, -15.386769 , 85 , 2019-07-26 02:39:18
];

And the paths are constructed with: 

Paths:
Load
        assetid,
                  '[' & concat( GeoMakePoint(latitude, if( longitude < 0 , longitude + 360, longitude)) , ',', messagetime ) & ']' as trail
Resident SmallData
Group By assetid;

After applying the transformation:  if( longitude < 0 , longitude + 360, longitude))

To make lines continue across the date line and not to wrap around, the coordinates has to "flow past" the date line.

See the app for an example.

Thanks,
