Hello,
I am trying to map multiple "suspect" lots on our manufacturing line with "TimeStamp" in X-axis and "Process Step" in the Y-axis. I wanted to superimpose tool maintenance "events" on this data. Ideally I wanted a similar look for the "event" as shown in the post Event Lines and Comments on Control Charts .
I am badly stuck trying to implement this on a graph builder. Any tips would be greatly appreciated. I am attaching a sample table. Trying to see if I can draw a vertical line for each date where there is an tool maintenance log by either using "Event_type" or "Event_Comment" column.
