Therefore, whether we are not wrong, we are intending to do a pre-work (tags, department, user) and show the specific tags on 1) a table or 2) a drop down box, thus these can be appended to a power chart. You **can** use an external Tag Browse Tree Component, in conjunction with the filter extension function, to filter the tags. Just not the one that is embedded in the Power Chart.

Moreover, the idea is, these graphs should be saved/ stored for further recalls/ retrieve. I have seen that there is into the Ignition Exchange an Ad Hoc Trends that helps in this functionality (save configuration - [Ignition Exchange | Inductive Automation](https://inductiveautomation.com/exchange/46/overview)). I assume whether there are large number of configured trends-graphs, these can be saved into a data base to storage them, and i… --- _[View the full topic](https://forum.inductiveautomation.com/t/powerchart-add-pens-via-script/41041)._
