Linking Axis.

Effectively, I have a situation where I have multiple

    > "traces" that I would like to display. Each trace
    > requires a separate subplot with a different Y-axis,
    > but all subplots should share the exact same X-axis.
    > I'd like to be able to interactively explore these
    > plots without fear of the subplots becoming
    > out-of-sync.

Use the sharex or sharey attribute of the Axes

    ax1 = subplot(211)

    ax2 = subplot(212, sharex=ax1)
    ax2.plot(something, else)

See examples/ for a complete example. Now when you
pan or zoom on either subplot, the two x axes remain in sync.

Neat stuff! Thanks to Baptiste Carvello for providing this feature.
