I believe you can achieve what you want with the ChartZoomManager by setting an axis constraint strategy that always returns horizontal (or only returns that if you are within the plot area or axis if you want). There is a org.gillius.jfxutils.chart.ChartZoomManager#setAxisConstraintStrategy used with mouse drag events, and org.gillius.jfxutils.chart.ChartZoomManager#setMouseWheelAxisConstraintStrategy used with wheel events.

hi, thanks for your repl. I have self solved this problem. but its only a point, For me, in order to not modify your lib, i have create classes to extend Chart JFXChartUtils and PayManager to modify something fpr panManager and chartZommManager, that i want to. Because from pinmanager instance i cant do that.

So i am thinking, whether its good, that user can directly get pinManager and chartZoomManager instance to modify that. image
