-## jquery.flot.hover.js
-
-This plugin is used for mouse hover and tap on a point of plot series.
-It supports the following options:
-```js
-grid: {
- hoverable: false, //to trigger plothover event on mouse hover or tap on a point
- clickable: false //to trigger plotclick event on mouse hover
-}
-```
-
-It listens to native mouse move event or click, as well as artificial generated
-tap and touchevent.
-
-When the mouse is over a point or a tap on a point is performed, that point or
-the correscponding bar will be highlighted and a "plothover" event will be generated.
-
-Custom "touchevent" is triggered when any touch interaction is made. Hover plugin
-handles this events by unhighlighting all of the previously highlighted points and generates
-"plothovercleanup" event to notify any part that is handling plothover (for exemple to cleanup
-the tooltip from webcharts).
