+/* Flot plugin for showing crosshairs when the mouse hovers over the plot.
+
+Copyright (c) 2007-2013 IOLA and Ole Laursen.
+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.
