Thanks for claryfing your objectives! In this case, you can add a custom property to zooming object, for example
customZoomType, which then can be acessed from mouse wheel zoom plugin as the zoom type property. This way, there won't be any zooming or selection enabled on the chart, besides the mouse wheel. Notice that you need to change the
zoomX and
zoomY inside the plugin so it can work this way.
