Hidden memory-limit for scatter plots?

Question

When trying to create a scatterplot for certain rasters (e.g. UAV orthophoto with 4.4 cm GSD, 8bit, 12299x10730 px), I get an error message "Not enough memory to create the chart".

We were able to replicate the error with different datasets and workstations (64GB to 128 RAM, NVDIA Quadro RTX 4000 and 5000). All produce the same error, while Task Manager shows that memory or other resources are nowhere near the limit.

I contacted Esri Germany's support and they were able to replicate the error (also for feature layers) but could not resolve it. They suspect that there is a fixed memory reservation for data to be processed for scatter plots, but it is not shown anywhere.

Do you have any ideas? Can you reproduce the "bug" or am I missing something?

Hi @BenjaminHaske ,

Thanks again for sending along the data. Just following up to let you know that this will be fixed in Pro version 3.3.

Take care,

Chris

Hi Chris,

thank you for your support. The "bug" appeared in a task for our students this semester. We were initally using ArcGIS Pro 3.2.1, but because it did not occur in the last semesters, I also tried the versions 3.0.6 and 3.1.4. with the same result. The datasets for the last semesters must have been slightly smaller.

The message displays after several minutes. If I use a smaller dataset, the correct scatter plot is displayed in seconds. The workaround for the students is to export the raster with a bigger resolution (e.g. 0.1 m x 0.1 m) and create the scatter plot then.

I will send you a data et with which I was able to reproduce the error (not the original raster, where the error first occurred).

Best regards

Benjamin
