Flot plugin for showing crosshairs, thin lines, when the mouse hovers

mode: null or "x" or "y" or "xy"

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 supports these options:
crosshair: {
mode: null or "x" or "y" or "xy"
color: color
lineWidth: number
}

The plugin also adds four public methods:
- setCrosshair(pos)
- 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.
