Good — that means the cube and morph are running fine, but the little live XYZ text isn’t updating.
Let’s clarify what “live” should mean before I show the correct code path.
In your current version the only place that calls update_xyz_display is inside setup_plot(), which happens once per redraw or during morph animation.
That means it only ever shows the last spiral point and never changes while you rotate or move the mouse.

To make it live, you need to:
* listen for motion_notify_event
* map the mouse position inside the 3-D axes to data coordinates
* update the text box continuously.

Below is a small self-contained replacement for the event and update logic that you can drop into your class.
It doesn’t change any of your geometry; it just adds a real-time coordinate readout that follows the mouse.

===== Put it anywhere under the existing methods: =====

<syntaxhighlight lang="python">    def on_motion(self, event):
        """Update XYZ display live as the mouse moves over the 3-D axes."""
        if event.inaxes != self.ax or event.xdata is None or event.ydata is None:
            return

        # Convert 2-D mouse to 3-D data coords (approximate)
        # We use the inverse of the current view transform
        try:
            x, y = event.xdata, event.ydata
            # Use z=0 plane approximation for simplicity
            z = 0.0
            self.update_xyz_display((x, y, z))
        except Exception:
            pass

</syntaxhighlight>

===== <syntaxhighlight lang="python">    def connect_events(self): =====
        """Connect mouse scroll and motion events."""
        self.fig.canvas.mpl_connect('scroll_event', self.on_scroll)
        self.fig.canvas.mpl_connect('motion_notify_event', self.on_motion)

</syntaxhighlight>

===== <syntaxhighlight lang="python">    def update_xyz_display(self, point): =====
        x, y, z = point
        self.text_box.set_text(f"X: {x:+.2f}\nY: {y:+.2f}\nZ: {z:+.2f}")
        self.fig.canvas.draw_idle()

</syntaxhighlight>

===== - When you move the mouse across the 3-D plot, the little box in the lower-right corner updates continuously. =====
* During morph animation it still reports the endpoint coordinates as before.
* No effect on rotation, morphing, or special views.

This version is pure ASCII, no encoding problems.
If you’d like the XYZ readout to display the coordinates under the mouse cursor projected on the cube faces instead of a simple (x, y, 0) plane estimate, I can extend it to do that using the full 3-D transform math. Would you like that next?
