LineChart<String, Number> not supported.

[ghost]

Using a LineChart with a String in either x or y axis will cause the ChartZoomManager to break.

Exception in thread "JavaFX Application Thread" java.lang.ClassCastException: javafx.scene.chart.CategoryAxis cannot be cast to javafx.scene.chart.ValueAxis
at org.gillius.jfxutils.chart.ChartZoomManager.(ChartZoomManager.java:137)

Right now the library is meant to work with numerical axes only, so I assume value axis. I'm not sure it makes sense to zoom on category axes, but perhaps it could make sense to allow zooming constrained to the one ValueAxis if only X or Y is a value axis. That would be quite useful for charts showing states over time (like on/off, etc.) Is that what you are looking for?

Jason,
I just added a right-click context menu to my chart.  Unfortunately, when I drag the chart around with the right button, it ends the drag by opening the context menu.  Oops.  I think  have a solution, but I haven't tested it.
org.gillius.jfxutils.chart.ChartPanManager line 82 should        mouseEvent.consume()   IF in fact we were doing a drag.   Unconsumed, the system pops up the menu.   release() could return a boolean so we know whether to consume the event.
I know--- back burner.  Me too.

Are you using the default mouse event filter that only handles primary button drags and ignores right clicks? But it sounds like you want it to pan with the right button if you drag but open menu if you don't. If I recall, jfxutils doesn't consume the events in most places.

Hi, Jason,

 If I recall, jfxutils doesn't consume the events in most places.
Righto.  I'm using a mouse event filter that uses left-drag for zooming and right-drag for panning.  I just now added a pop-up menu, and it springs to life after a pan.  Oops.   My workaround is to use middle-drag for panning instead.  Good enough for me for now, but I'm thinking that the right solution is to consume the right-drag release events, and don't consume the right-nodrag release events.  Then the JavaFx can fire up the pop-up menu if not consumed.

Just thought I'd mention one other thing for the eventual re-write ;)---  the mouse event filter's logic is a bit backward-- it consumes the event to tell JfxUtil NOT to act.  /** A JfxUtil filter that accepts only a simple, single-click MIDDLE drag without modifiers. consume() tells JfxUtils.jar to reject, oddly! */ public static final EventHandler SIMPLE_MIDDLE = ev -> { if (!JfxUtil.isDrag(ev, MouseButton.MIDDLE, 1)) ev.consume(); };
