  Flot plugin for adding panning and zooming capabilities to a plot.
  
  The default behaviour is double click and scrollwheel up/down to zoom
  in, drag to pan. The plugin defines plot.zoom({ center }),
  plot.zoomOut() and plot.pan(offset) so you easily can add custom
  controls. It also fires a "plotpan" and "plotzoom" event when
  something happens, useful for synchronizing plots.
  
  Options:
  
    zoom: {
      interactive: false
      trigger: "dblclick" // or "click" for single click
      amount: 1.5         // 2 = 200% (zoom in), 0.5 = 50% (zoom out)
    }
  
    pan: {
      interactive: false
      cursor: "move"      // CSS mouse cursor value used when dragging, e.g. "pointer"
      frameRate: 20
    }
  
    xaxis, yaxis, x2axis, y2axis: {
      zoomRange: null  // or [number, number] (min range, max range) or false
      panRange: null   // or [number, number] (min, max) or false
    }
  
  "interactive" enables the built-in drag/click behaviour. If you enable
  interactive for pan, then you'll have a basic plot that supports
  moving around; the same for zoom.
  
  "amount" specifies the default amount to zoom in (so 1.5 = 150%)
  relative to the current viewport.
  
  "cursor" is a standard CSS mouse cursor string used for visual
  feedback to the user when dragging.
  
  "frameRate" specifies the maximum number of times per second the plot
  will update itself while the user is panning around on it (set to null
  to disable intermediate pans, the plot will then not update until the
  mouse button is released).
  
  "zoomRange" is the interval in which zooming can happen, e.g. with
  zoomRange: [1, 100] the zoom will never scale the axis so that the
  difference between min and max is smaller than 1 or larger than 100.
  You can set either end to null to ignore, e.g. [1, null]. If you set
  zoomRange to false, zooming on that axis will be disabled.
  
  "panRange" confines the panning to stay within a range, e.g. with
  panRange: [-10, 20] panning stops at -10 in one end and at 20 in the
  other. Either can be null, e.g. [-10, null]. If you set
  panRange to false, panning on that axis will be disabled.
  
  Example API usage:
  
    plot = $.plot(...);
  
    // zoom default amount in on the pixel (10, 20)
    plot.zoom({ center: { left: 10, top: 20 } });
  
    // zoom out again
    plot.zoomOut({ center: { left: 10, top: 20 } });
  
    // zoom 200% in on the pixel (10, 20)
    plot.zoom({ amount: 2, center: { left: 10, top: 20 } });
  
    // pan 100 pixels to the left and 20 down
    plot.pan({ left: -100, top: 20 })
  
  Here, "center" specifies where the center of the zooming should
  happen. Note that this is defined in pixel space, not the space of the
  data points (you can use the p2c helpers on the axes in Flot to help
  you convert between these).
  
  "amount" is the amount to zoom the viewport relative to the current
  range, so 1 is 100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is
  70% (zoom out). You can set the default in the options.
