-/* Flot plugin for selecting regions of a plot.
-
-Copyright (c) 2007-2013 IOLA and Ole Laursen.
-Licensed under the MIT license.
-
-The plugin supports these options:
-
-selection: {
-        mode: null or "x" or "y" or "xy",
-        color: color,
-        shape: "round" or "miter" or "bevel",
-        minSize: number of pixels
-}
-
-Selection support is enabled by setting the mode to one of "x", "y" or "xy".
-In "x" mode, the user will only be able to specify the x range, similarly for
-"y" mode. For "xy", the selection becomes a rectangle where both ranges can be
-specified. "color" is color of the selection (if you need to change the color
-later on, you can get to it with plot.getOptions().selection.color). "shape"
-is the shape of the corners of the selection.
-
-"minSize" is the minimum size a selection can be in pixels. This value can
-be customized to determine the smallest size a selection can be and still
-have the selection rectangle be displayed. When customizing this value, the
-fact that it refers to pixels, not axis units must be taken into account.
-Thus, for example, if there is a bar graph in time mode with BarWidth set to 1
-minute, setting "minSize" to 1 will not make the minimum selection size 1
-minute, but rather 1 pixel. Note also that setting "minSize" to 0 will prevent
-"plotunselected" events from being fired when the user clicks the mouse without
-dragging.
-
-When selection support is enabled, a "plotselected" event will be emitted on
-the DOM element you passed into the plot function. The event handler gets a
-parameter with the ranges selected on the axes, like this:
-
-        placeholder.bind( "plotselected", function( event, ranges ) {
-                alert("You selected " + ranges.xaxis.from + " to " + ranges.xaxis.to)
-                // similar for yaxis - with multiple axes, the extra ones are in
-                // x2axis, x3axis, ...
-        });
-
-The "plotselected" event is only fired when the user has finished making the
-selection. A "plotselecting" event is fired during the process with the same
-parameters as the "plotselected" event, in case you want to know what's
-happening while it's happening,
-
-A "plotunselected" event with no arguments is emitted when the user clicks the
-mouse to remove the selection. As stated above, setting "minSize" to 0 will
-destroy this behavior.
-
-The plugin allso adds the following methods to the plot object:
-
-- setSelection( ranges, preventEvent )
-
-  Set the selection rectangle. The passed in ranges is on the same form as
-  returned in the "plotselected" event. If the selection mode is "x", you
-  should put in either an xaxis range, if the mode is "y" you need to put in
-  an yaxis range and both xaxis and yaxis if the selection mode is "xy", like
-  this:
-
-        setSelection({ xaxis: { from: 0, to: 10 }, yaxis: { from: 40, to: 60 } });
-
-  setSelection will trigger the "plotselected" event when called. If you don't
-  want that to happen, e.g. if you're inside a "plotselected" handler, pass
-  true as the second parameter. If you are using multiple axes, you can
-  specify the ranges on any of those, e.g. as x2axis/x3axis/... instead of
-  xaxis, the plugin picks the first one it sees.
-
-- clearSelection( preventEvent )
-
-  Clear the selection rectangle. Pass in true to avoid getting a
-  "plotunselected" event.
-
-- getSelection()
-
-  Returns the current selection in the same format as the "plotselected"
-  event. If there's currently no selection, the function returns null.
