Hi ignition crew!

Not sure where to post / outlet this, but the docs seem to be missing the system.dataset.filter function 🙂

Can anyone give me a steer of where to send / outlet this info?

Thanks!  
Alex

I don't think there's a `system.dataset.filter`.  
Are you thinking of `filterColumns` ?

> **[system.dataset.filterColumns | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-dataset/system-dataset-filterColumns)**
>
> Takes a dataset and returns a view of the dataset containing only the columns found within the given list of columns.

Supposedly it does exist according to the type hinting! 🙂  
...and would be very useful for my current task 👀

Is that a function from Paul's ignition extensions module?

Esit: Yes it is, hence won't be in the user manual [Ignition Extensions - Convenience utilities for advanced users](https://forum.inductiveautomation.com/t/ignition-extensions-convenience-utilities-for-advanced-users/64615)
