gallery-isoline hasn't been updated in a while and it looks like there's a bug when using newer versions of YUI. Since there's some interest in it, I'll look at it this week.

I've made code updates to fix the issue in newer versions of YUI. Yogi says the next gallery CDN deployment isn't until next week, so here's the new version minified:

YUI.add("gallery-isoline",function(e,t){(function(e){"use strict";var t="dataCellHeight",n="dataCellWidth",r=Math,i=e.Shape,s=r.ceil,o=r.max,u=r.min,a=parseInt,f=function(){f.superclass.constructor.apply(this,arguments)};e.Isoline=e.extend(f,i,{redraw:function(){return this._draw(),this},_draw:function(){var e=this,r=e.get(t)||1,i=e.get(n)||1,f=r/2,l=i/2,c=e.get("height"),h=e.get("width"),p=e.get("dataFn"),d=u(e.get("dataMaxX")||h,h),v=u(e.get("dataMaxY")||c,c),m=o(e.get("dataMinX")||0,0),g=o(e.get("dataMinY")||0,0),y=s((d-m)/i),b=s((v-g)/r),w,E,S=0,x,T;e.clear();for(;S<b;S+=1)for(E=0;E<y;E+=1)w="",x=m+E*i,T=g+S*r,w+=p(x-l,T-f)?1:0,w+=p(x+l,T-f)?1:0,w+=p(x+l,T+f)?1:0,w+=p(x-l,T+f)?1:0,w=a(w,2),(w===5||w===10)&&!p(x,T)&&(w*=4),w===1||w===14?e.moveTo(x-l,T).lineTo(x,T+f):w===2||w===13?e.moveTo(x,T+f).lineTo(x+l,T):w===3||w===12?e.moveTo(x-l,T).lineTo(x+l,T):w===4||w===11?e.moveTo(x,T-f).lineTo(x+l,T):w===5||w===40?e.moveTo(x-l,T).lineTo(x,T-f).moveTo(x,T+f).lineTo(x+l,T):w===6||w===9?e.moveTo(x,T-f).lineTo(x,T+f):w===7||w===8?e.moveTo(x-l,T).lineTo(x,T-f):(w===10||w===20)&&e.moveTo(x,T-f).lineTo(x+l,T).moveTo(x-l,T).lineTo(x,T+f);e.end()}},{ATTRS:e.mix({dataCellHeight:{value:1},dataCellSize:{setter:function(e){return this._set(t,e),this._set(n,e),e},value:1},dataCellWidth:{value:1},dataFn:{value:function(){return!1}},dataMaxX:{value:null},dataMaxY:{value:null},dataMinX:{value:null},dataMinY:{value:null}},i.ATTRS),NAME:"isoline"})})(e)},"",{requires:["graphics"]});

and the new version used in the two examples with YUI 3.10.2:
