-/* Flot plugin for showing crosshairs when the mouse hovers over the plot.
-

-Licensed under the MIT license.
-
-The plugin supports these options:
-
-        crosshair: {
-                mode: null or "x" or "y" or "xy"
-                color: color
-                lineWidth: number
-        }
-
-Set the mode to one of "x", "y" or "xy". The "x" mode enables a vertical
-crosshair that lets you trace the values on the x axis, "y" enables a
-horizontal crosshair and "xy" enables them both. "color" is the color of the
-crosshair (default is "rgba(170, 0, 0, 0.80)"), "lineWidth" is the width of
-the drawn lines (default is 1).
-
-The plugin also adds four public methods:
-
-  - setCrosshair( pos )
-
-    Set the position of the crosshair. Note that this is cleared if the user
-    moves the mouse. "pos" is in coordinates of the plot and should be on the
-    form { x: xpos, y: ypos } (you can use x2/x3/... if you're using multiple
-    axes), which is coincidentally the same format as what you get from a
-    "plothover" event. If "pos" is null, the crosshair is cleared.
-
-  - clearCrosshair()
-
-    Clear the crosshair.
-
-  - lockCrosshair(pos)
-
-    Cause the crosshair to lock to the current location, no longer updating if
-    the user moves the mouse. Optionally supply a position (passed on to
-    setCrosshair()) to move it to.
-
-    Example usage:
-
-        var myFlot = $.plot( $("#graph"), ..., { crosshair: { mode: "x" } } };
-        $("#graph").bind( "plothover", function ( evt, position, item ) {
-                if ( item ) {
-                        // Lock the crosshair to the data point being hovered
-                        myFlot.lockCrosshair({
-                                x: item.datapoint[ 0 ],
-                                y: item.datapoint[ 1 ]
-                        });
-                } else {
-                        // Return normal crosshair operation
-                        myFlot.unlockCrosshair();
-                }
-        });
-
-  - unlockCrosshair()
-
-    Free the crosshair to move again after locking it.
