Lock y-axis movement for stacked scales when paning

[nilsakesson]

Im having a stacked scale plot where I want to be able to lock y axis movement for the axis that I'm in. If im paning in axis 2 I should be able to pan in both x and y direction while axis 1 is just moving in x-direction. For zooming the funcionality could be the same. Consider the axes separated and lock x-direction only with the shared x-axis while the y-axes are free moving depending on where the mouse is.
