- <p>With the navigate plugin it is easy to add panning and zooming.
- Drag to pan, double click to zoom (or use the mouse scrollwheel).</p>
-
- <p>The plugin fires events (useful for synchronizing several
- plots) and adds a couple of public methods so you can easily build
- a little user interface around it, like the little buttons at the
- top right in the plot.</p>
