I want to make an visual design on Grafana with my PI Values. I am using Basic Authentication and Server Access, I can connect PI Web API. I can see my elements and attributes on Grafana Dashboard. But I can’t get my values, I don’t know why. I know the data isn’t null. So I checked my permissions on PI Web API user and I allowed all permissions. I added Anonymous Authentication too. But nothing changed. I think the problem isn’t on Osisoft. Could you help me about this?
