-/* Flot plugin for thresholding data.

-The plugin supports these options:
-
-        series: {
-                threshold: {
-                        below: number
-                        color: colorspec
-                }
-        }
-
-It can also be applied to a single series, like this:
-
-        $.plot( $("#placeholder"), [{
-                data: [ ... ],
-                threshold: { ... }
-        }])
-
-An array can be passed for multiple thresholding, like this:
-
-        threshold: [{
-                below: number1
-                color: color1
-        },{
-                below: number2
-                color: color2
-        }]
-
-These multiple threshold objects can be passed in any order since they are
-sorted by the processing function.
-
-The data points below "below" are drawn with the specified color. This makes
-it easy to mark points below 0, e.g. for budget data.
-
-Internally, the plugin works by splitting the data into two series, above and
-below the threshold. The extra series below the threshold will have its label
-cleared and the special "originSeries" attribute set to the original series.
-You may need to check for this in hover events.
