I'm writing a rudimentary Candlestick chart class in which the candlesticks are created as Regions and are plotted by setting their layoutX and layoutY values to the getDisplayPosition() of the relevant axis.

For example, to plot a candlestick at value 3 on an X axis, I do this:

candlestick.setLayoutX(xAxis.getDisplayPosition(3));

When the stage resizes or when the axes are zoomed in or out, the candlesticks' layout values have to be reset so that the chart renders correctly. I'm currently handling this via ChangeListeners for resize events and Button.setOnAction()s for zooming.

However, I'd rather bind the candlesticks' layout properties to the axes' display positions than set/reset the layout values, but can't find a "displayPositionProperty" (or similar) for a NumberAxis.

Is it possible to do this? Which NumberAxis property would I bind to? ie.

candlestick.layoutXProperty().bind(xAxis.WHICH_PROPERTY?);

Also, would binding the properties be more efficient than resetting layout positions? Some of the charts could potentially have thousands of candlesticks but I can't test resource usage until I figure out how to code the bind.

I've experimented with scaling the candlesticks to the axes' scale but can't use that approach because scaling a Region affects its border width. For certain types of candlesticks, that can change its meaning.

I've also played with the Ensemble candlestick demo chart. It was useful in giving me a start but is too simplistic for my needs.

Here's a MVCE that demonstrates my approach. Any guidance re binding would be very much appreciated.
