15 Selection support is enabled by setting the mode to one of "x", "y" or "xy".
17 "y" mode. For "xy", the selection becomes a rectangle where both ranges can be
18 specified. "color" is color of the selection (if you need to change the color
19 later on, you can get to it with plot.getOptions().selection.color). "shape"
20 is the shape of the corners of the selection.
22 "minSize" is the minimum size a selection can be in pixels. This value can
23 be customized to determine the smallest size a selection can be and still
24 have the selection rectangle be displayed. When customizing this value, the
27 minute, setting "minSize" to 1 will not make the minimum selection size 1
32 When selection support is enabled, a "plotselected" event will be emitted on
43 selection. A "plotselecting" event is fired during the process with the same
48 mouse to remove the selection. As stated above, setting "minSize" to 0 will
55 Set the selection rectangle. The passed in ranges is on the same form as

76 Returns the current selection in the same format as the "plotselected"
77 event. If there's currently no selection, the function returns null.
