Arcade - Replacing null values with a custom value within a dictionnary

RemyOlive — Tue, 30 Apr 2024 11:56:16 GMT

Hello everyone,

I'm very new to Arcade, and am working to populate an indicator from multiple feature layers.

My problem is that I have a value, called "ArrivalTime" (which is a number) that some layers have, and others don't. When I execute the code, the layers that do not have an "ArrivalTime" show this value as "null" and I cannot filter based on it, they just get excluded automatically.

My question is, I'd like to replace this "null" value by a 0, so that I can filter on them the same as the layers that do have an "ArrivalTime" value.

Here is the code, as the Canada layers do not have any "ArrivalTime" value, I'm trying to force a 0 as the default value (line 19), but it keeps on returning a null value.

Here is an example of the return table that I get.

Any help would be appreciated,

Thanks a lot,

Rémy

The dictionary contained the field "ArrivalTime" but you were assigning 0 to "Arrival_Time".

for (var t in Length_Canada) { combinedDict.features[i++] = { attributes: { Shape_Length: t["Shape__Length"], ArrivalTime: 0 }, geometry: Geometry(t) }; }
