I am wanting to build a trend in a PI Vision dashboards using the Calculations feature. I am looking to calculate weekly average data. However, for the 'Columns' in Calculations the only one that works is 'Value', none of the other work (e.g. 'Average', 'Maximum', 'Minimum', etc.) and returns 'No Data'. Is there any way I can fix this? What is causing the error? Is it the data coming in? Am I not using the Calculations feature correctly?
I have included screenshots of my trends, and the advanced options for the calculation.
