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.

If you don't + want that to happen, e.g. if you're inside a "plotselected" handler, pass + true as the second parameter.
