-/* 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.
