-/* Flot plugin for showing crosshairs when the mouse hovers over the plot.
-
-Copyright (c) 2007-2014 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.
