In this instance I think you may actually want [system.tag.queryTagCalculations](https://docs.inductiveautomation.com/display/DOC80/system.tag.queryTagCalculations).

Either way the functions return a dataset, you can get the desired value from the dataset and put it into the label from what ever script you choose.

Something like this (assuming Vision):

```auto
if event.propertyName == 'some property':
	tagCalcs = system.tag.queryTagCalculations(paths = ['Your Tag Path'],calculations = ['Average'],rangeHours = 24)
	event.source.parent.parent.getComponent('Numeric Label').value = tagCalcs.getValueAt(0,0)

```
