I'm trying to store the median value of some tag historian data in an expression tag. I'm doing this with the system.tag.queryTagHistory function. I was looking through the documentation and it doesn't seem to support median as an aggregate. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/1/119657310637d28474e6d1b949703acb9b8e66e1.png) Is there an easy way around this? Thanks. ---
