As Victor mentioned what you can do with ChartPanAndZoomBehavior
is to limit the pan and/or zoom to horizontal through the Pan and Zoom modes, which is explained here
. If I understand correctly, your scenario differs in a way that you want to be able to zoom in both directions, but the vertical zoom should not be on the place of the gesture, but on the place of the series, which is not currently supported and differs from this behavior's implementation.
