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(e){function n(e,t,n,r){if(!t.points.errorbars)return;var i=[{x:!0,number:!0,required:!0},{y:!0,number:!0,required:!0}],s=t.points.errorbars;if(s=="x"||s=="xy")t.points.xerr.asymmetric?(i.push({x:!0,number:!0,required:!0}),i.push({x:!0,number:!0,required:!0})):i.push({x:!0,number:!0,required:!0});if(s=="y"||s=="xy")t.points.yerr.asymmetric?(i.push({y:!0,number:!0,required:!0}),i.push({y:!0,number:!0,required:!0})):i.push({y:!0,number:!0,required:!0});r.format=i}function r(e,t){var n=e.datapoints.points,r=null,i=null,s=null,o=null,u=e.points.xerr,a=e.points.yerr,f=e.points.errorbars;f=="x"||f=="xy"?u.asymmetric?(r=n[t+2],i=n[t+3],f=="xy"&&(a.asymmetric?(s=n[t+4],o=n[t+5]):s=n[t+4])):(r=n[t+2],f=="xy"&&(a.asymmetric?(s=n[t+3],o=n[t+4]):s=n[t+3])):f=="y"&&(a.asymmetric?(s=n[t+2],o=n[t+3]):s=n[t+2]),i==null&&(i=r),o==null&&(o=s);var l=[r,i,s,o];return u.show||(l[0]=null,l[1]=null),a.show||(l[2]=null,l[3]=null),l}function i(e,t,n){var i=n.datapoints.points,o=n.datapoints.pointsize,u=[n.xaxis,n.yaxis],a=n.points.radius,f=[n.points.xerr,n.points.yerr],l=!1;if(u[0].p2c(u[0].max)u[1].max||yu[0].max)continue;if(f[v].err=="y")if(g>u[0].max||gu[1].max)continue;var E=!0,S=!0;b>m[1]&&(E=!1,b=m[1]),w0&&T>0){var N=T/2;t.lineWidth=N,t.strokeStyle="rgba(0,0,0,0.1)",s(t,f[v],g,y,b,w,E,S,a,N+N/2,m),t.strokeStyle="rgba(0,0,0,0.2)",s(t,f[v],g,y,b,w,E,S,a,N/2,m)}t.strokeStyle=f[v].color?f[v].color:n.color,t.lineWidth=x,s(t,f[v],g,y,b,w,E,S,a,0,m)}}}}function s(t,n,r,i,s,u,a,f,l,c,h){i+=c,s+=c,u+=c,n.err=="x"?(s>r+l?o(t,[[s,i],[Math.max(r+l,h[0]),i]]):a=!1,ui+l?o(t,[[r,Math.max(i+l,h[1])],[r,u]]):f=!1),l=n.radius!=null?n.radius:l,a&&(n.upperCap=="-"?n.err=="x"?o(t,[[s,i-l],[s,i+l]]):o(t,[[r-l,s],[r+l,s]]):e.isFunction(n.upperCap)&&(n.err=="x"?n.upperCap(t,s,i,l):n.upperCap(t,r,s,l))),f&&(n.lowerCap=="-"?n.err=="x"?o(t,[[u,i-l],[u,i+l]]):o(t,[[r-l,u],[r+l,u]]):e.isFunction(n.lowerCap)&&(n.err=="x"?n.lowerCap(t,u,i,l):n.lowerCap(t,r,u,l)))}function o(e,t){e.beginPath(),e.moveTo(t[0][0],t[0][1]);for(var n=1;n
