The interactive plot requires a browser with JavaScript and HTML 5 canvas support.

Select a region with data to zoom. Select a region with no data or click the mouse on the plot to revert to the orginal display.

Moving the mouse pointer over or near a point will display the coordinates of the point. The number of digits shown do not reflect the uncertainty of the value.

On newer browsers the following keyboard commands are supported:

Key	Action
L	Toggle log-log display if possible.
S	Toggle semilog (log Y) display if possible.
K	Move / hide legend (key). Repeated presses of this key will posiiton the legend in the following sequence: upper left, upper right, lower right, lower left, hidden.

Click in or tab to the plot area to enable keyboard commands.

The following components were used in generating the plot:

• jQuery
• jQuery UI
• Flot
• Plugins for Flot:
  • Resize (distributed with Flot)
  • Selection (distributed with Flot)
  • Axis labels

Additonal code used was developed at NIST: plot-data.js.
