I am posting this question on behalf of a user at our site. She has created a PI Vision 2019 display (attached) and implemented multiple scales and Trace options in the Format Trend. On the left side of the graphs it appears the data is repeated (circled in red). When I check the archived data there are no repeating values but she is convinced the data is not correct. It appears to me some behavior in Vision that is creating the "double vision" on the left. Has anyone seen this before or can explain?
