I have some problems with XYPLOT, every time that I create a XY, the graph doesn't work, and then this log appear, look at the images:
I've had similar problems, and in your case it looks like the PI WebAPI service is not running.
Start it and check again!
There is a known issue in PI WebAPI 2017 R2 where the service will stop when a lot of errors occur at the same time. I had a display with 4 XY plots, each with 1 X-value and 8 Y-values, and when these values couldn't be found because I had moved the location of the elements in PI AF, the service would crash when I loaded the display. (This issue is addressed in PI WebAPI 2018)
I have the same issue and restarting the PI Web API service did not really help. Please let me know if a self signed certificate causes an issue or if there are any specific permissions to be set on Data Archive. The account with which the PI Web API service is running already has access to the PI Data Archive
It's difficult to say without more details, but in your case I would recommend you open a case with OSIsoft to debug this. If you want to continue here in the forums, you should create a new thread and provide all details!
Thank you Asle.
I just opened a case with tech support.
