JavaFx 8 WindowEvent doesn't provide the (x,y) location of the mouse, unfortunately. I solved this (and it works fine) by using the AWT MouseInfo like this:

Tooltip t = new Tooltip();
Tooltip.install(yournode, t);
t.setOnShowing(ev -> {// called just prior to being shown
                Point mouse = java.awt.MouseInfo.getPointerInfo().getLocation();
                Point2D local = yournode.screenToLocal(mouse.x, mouse.y);

                // my app-specific code to get the chart's yaxis value
                // then set the text as I want
                double pitch = yaxis.getValueForDisplay(local.getY()).doubleValue();
                double freq = AudioUtil.pitch2frequency(pitch);
                t.setText(String.format("Pitch %.1f:  %.1f Hz   %.1f samples", pitch, freq, audio.rate / freq));
        });
