/* Flot plugin for plotting error bars.

Error bars are used to show standard deviation and other statistical
properties in a plot.

* Created by Rui Pereira  -  rui (dot) pereira (at) gmail (dot) com

This plugin allows you to plot error-bars over points. Set "errorbars" inside
the points series to the axis name over which there will be error values in
your data array (*even* if you do not intend to plot them later, by setting
"show: null" on xerr/yerr).

The plugin supports these options:

series: {
		points: {
			errorbars: "x" or "y" or "xy",
			xerr: {
				show: null/false or true,
				asymmetric: null/false or true,
				upperCap: null or "-" or function,
				lowerCap: null or "-" or function,
				color: null or color,
				radius: null or number
			},
			yerr: { same options as xerr }
		}
	}

Each data point array is expected to be of the type:

"x"  [ x, y, xerr ]
	"y"  [ x, y, yerr ]
	"xy" [ x, y, xerr, yerr ]

Where xerr becomes xerr_lower,xerr_upper for the asymmetric error case, and
equivalently for yerr. Eg., a datapoint for the "xy" case with symmetric
error-bars on X and asymmetric on Y would be:

[ x, y, xerr, yerr_lower, yerr_upper ]

By default no end caps are drawn. Setting upperCap and/or lowerCap to "-" will
draw a small cap perpendicular to the error bar. They can also be set to a
user-defined drawing function, with (ctx, x, y, radius) as parameters, as eg.

function drawSemiCircle( ctx, x, y, radius ) {
		ctx.beginPath();
		ctx.arc( x, y, radius, 0, Math.PI, false );
		ctx.moveTo( x - radius, y );
		ctx.lineTo( x + radius, y );
		ctx.stroke();
	}

Color and radius both default to the same ones of the points series if not
set. The independent radius parameter on xerr/yerr is useful for the case when
we may want to add error-bars to a line, without showing the interconnecting
points (with radius: 0), and still showing end caps on the error-bars.
shadowSize and lineWidth are derived as well from the points series.

(function ($) {
    var options = {
        series: {
            points: {
                errorbars: null, //should be 'x', 'y' or 'xy'
                xerr: { err: 'x', show: null, asymmetric: null, upperCap: null, lowerCap: null, color: null, radius: null},
                yerr: { err: 'y', show: null, asymmetric: null, upperCap: null, lowerCap: null, color: null, radius: null}
            }
        }
    };

            { x: true, number: true, required: true },
