Elevation Profile Widget Flattening Issue in AGOL

[JCOSGIS]

Hi all,

In ArcGIS Online Experience Builder, I’m seeing the Elevation Profile widget flatten out when a drawn or selected trail exceeds a certain length, even though the trail has noticeable elevation changes. Shorter segments look fine, but once the profile hits a certain distance, the detail drops off.

I’ve tested this using both the Esri World Elevation Service and my own 10m DEM published for use in the Web Scene Viewer — same result in AGOL.

What’s odd is that I built this exact same application in Portal (ArcGIS Enterprise 11.1), which uses Experience Builder 1.10, and the issue doesn’t occur there — the profile remains detailed across the entire trail length.

Has anyone else run into this? Is this a known regression in the newer ArcGIS Online Elevation Profile widget (Experience Builder 1.18), or is there a setting to control sampling resolution?

Screenshots attached for comparison between AGOL and Portal outputs.

Screenshots attached:

1. AGOL – Short segment (works fine)

2. AGOL – Longer segment (flattening occurs)

3. Portal – Older EB version (no issue)

Thanks!
