Mechanism to detect clicks on plot area and axis separately?

[bryaan]

How can I detect clicks on only the xaxis? How about only on the plot area where series go?

I have tried:

is_mouseinside(ax.scene)

But that detects either axis and also triggers for clicks inside the plot area.
I need the xaxis and plot area separately.

is_mouseinside just checks if the mouse is within scene.viewport. Other than checking for areas you can use pick() to check for plots, but that's it
