+/* 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.
