Raster values in legend not honouring DRA

[MattHowe]

I'm using a single band raster in a new layout and have activated DRA so the stretch only uses the data within the view extent. In the legend it looks like the values aren't adjusted as per the DRA. Is this a bug or is there a way to adjust the values of the raster in the legend automatically to reflect the cell values shown in the current view only?

Hi Howeitzer, 

It is possible that you are running into a known issue - 

BUG-000112368: Raster statistics fail to update dynamically with display extent when using stretched symbology imagery and dynamic range adjustment (DRA) in ArcGIS Pro.

To confirm this please contact support. They can confirm that this is the same issue or help enter a new issue if your scenario is different. They can be contacted at https://support.esri.com/en/contact-tech-support.

Thanks Tom I'll report the issue via the link. As a quick workaround I clipped the raster using raster functions.

@MattHowe it looks like this one has been promoted to "In the Product Plan". So hopefully we'll see an update in the next release or two

It's my understanding that this issue was rectified sometime in 2023. Is anyone still having this issue now, in 2024?

I'm still having this issue unfortunately even though Pro is all up to date

My statistics in the Table of Contents seem to be updating correctly, but the symbology in the map is not updating correctly as I change scales and extents.  At some scales and extents it seems to be correct but not at others.  I'm at Pro Version 3.3.1.

This one's a doozy! I am attempting to utilize DRA with raster datasets in order to automatically update a dynamic legend with DRA values based on where I want to pan for my final map. While the DRA values are being seen in the statistics, they are unfortunately not showing in the dynamic legend unless I take additional steps - such as checking and unchecking Invert in the symbology pane - to force the values to be updated. The ToC seems to be even more stubborn and while the correct DRA values will flicker for a second in the ToC, they end up disappearing and the full Dataset values show up again - in none of my steps were the proper DRA values shown permanently in the ToC. Does anyone have an explanation as to what is going on?

In addition to the ToC not updating and therefore not properly updating dynamic legend values on-the-fly, I have also attempted to use DRA and dynamic legends with Map Series and I am getting some... interesting results. Please see the attached annotated screenshot mosaic for further information.

@TomBole I am currently using v3.3.0 and running into this issue despite the bug being marked as fixed in v3.0 - thoughts?

Thanks @SeanGarner for posting on this and the screen captures for the DRA error from you post above 👍 nice to see other people embrace the use of SnagIT for communication and documenting errors. 

We are also seeing the same thing on our end while using dynamic range adjustment (DRA). Running the latest version of ArcGIS Pro 3.3.0.

It is not updating correctly and we have to click around to force the refresh 🤷‍

If you are on this thread please chime in and confirm you are seeing the same thing. 

@TomBole I know this bug was closed back in 2021.... Is it not possible that it was accidentally broken again by some other update since then? 

[JamieDodd]

Thanks yes, my issue never resolved.
