How to know which stream called?

Hello,

I’m feeding multiple streams into a DynamicMap. One of those streams is a RangeXY. My aim is to distinguish between the user applied change of the axis limits, which makes the RangeXY stream change and call the callable provided to the DynamicMap, and changes to the axes limits, because the other stream has changed the plotted data and the axes ranges where reset automatically.

Would anyone know a method how to distinguish in the DynamicMap’s callable which stream has changed so that the callable was executed?
