I added a field to a hosted feature layer and populated both the Field Name and Display Name, but the Field Name, not the Display Name, appear when configuring a bar chart in Web App Builder. The chart is now labeled using the Field Name, which does not seem correct since the Display Name should act like a field alias. Has anyone noticed this behavior? Your help is appreciated.
I have tried to replicate this and I am unable to I see the display name where you have highlighted in the third screenshot.
When you added the new field was the web app builder already created? If so can you make a new web app builder to see if the issue is persistent? I would remove and readd the web map if the issue is not happening in a new project.
What about Experience Builder does the same happen here?
If you look at the third screen capture, what I circled in red is the field name, not the display name. The display name should appear if it worked as intended. I have not tried to replicate in Experience Builder, as Experience Builder does not have full functionality that I need. ESRI was able to duplicate the issue, so I believe this is an issue with AGOL and not with WAB or ExB.
