[BUG?] Perspective Power Chart - Time series unequal major gap

Yeah, it seems like getZoomedScaleBounds() only returns the scales that have been zoomed. If you allow for panning and zooming on both axes then you'll have data for both x and y (and presumably y2 and y3 as well). Yup that's exactly it, you can't write undefined to a property. This is a good place to use JavaScript's ?? coalescing operator.

The NPE is coming from trying to assign undefined to a PropertyTree node, the solution is to make sure all the properties exist before writing.
