I would like to know if it's possible to create a mouse zoom Event to do a X zoom/unzoom on the mouse wheel event ? Or is-it necessary to catch Windows events and to propagate them to Quinn-Curtis component ? Instead these automatic solutions, I can change my datas.
There is no built-in support for support of the mouse wheel while zooming. We don't how this would work, since our zooming function is a two dimensional action, based on both x and y mouse movement, and the mouse wheel is a one-dimensional input device. I suppose you could enforce a fixed aspect ratio, but this is much more common in maps, compared typical chart data. You would have to try and intercept the mouse wheel events in the ChartView, then re-issue them as mouse move events. We have never done it though, and don't have any examples.
