Hello, I need to create a report that includes a **dynamic Timeseries chart** (by default, it doesn’t know what it should display). I’ve already reviewed several forum discussions and explored aspects of the JFreeChart API, but I haven’t made any progress. I’d like to know if this is possible, and if it is, **I’d appreciate it if someone could provide an example**.

I’m working with Ignition version 8.1.37 and Reporting Module version 6.1.37 (Trial).

_Thank you in advance_

It involves a non-trivial amount of scripting, because you have to do with scripting all the Ignition -\> JFreeChart stuff that we're automatically doing for you "under the hood", but it is possible.  
This thread is probably a reasonable starting point:

The solution below does not do anything (commented with # added ) [image] I almost have a dynamic reporting chart. (supplying variable amount of pens into a reporting chart.
