I need to let the operator choose two points on a chart (like 8AM an 11AM) and it would show the xtrace line for each time stamp. I tried this module below , but I couldnt make it do what i need.

Notechart can only show one X-Trace (with values) at a time, same as the built-in charts. Notechart does allow you to place (many) timestamped annotations wherever you wish, and the operator can click on them to accurately activate X-Trace at that point. The mouse events in Notechart have the extra event property `domainTS` that holds the timestamp you need to script the creation of an annotation. Annotations can be supplied in either of two datasets, `notes` and `altNotes`, for programmer convenience (bind one to a DB query, use the other for scripting, perhaps). Putting two complete X-Traces with values would be rather difficult, with all of the spacing/scaling/non-overlap calculations involved. ---

Two x-traces is pretty common though, Factory Talk, Wonderware Intouch, Citect Process Analyst, Pi, all let you have two cursors or x-traces and then can show you the value of the time series at each one or the change from one to the next. ---

I’ve mentioned this sort of thing before as well, but as a request for the stock easy chart component. I posted it to the ideas section for people to vote on.

I voted! Thanks. We were able to come up with a workaround, but its not perfect. We are doing a migration from WW, and the old system had the functionality.
