There doesn't seem to be any way to constrain x- or y- axis when panning/zooming in IPython interactive (%matplotlib nbagg) mode. Is there? If not, I'd like to request this feature.

Also it is helpful to somehow to set a default constraint when plotting the figure. In time series plots with linked axes, for example, I generally just want to allow x-axis (really t-axis) zooming and panning, and I want to leave the y-axis limits untouched. I don't want the default behavior to allow zooming and panning to affect the y-axis, I want the user to have to select something to allow it if they really want.

(by the way %matplotlib nbagg is AWESOME!!!!)
