带环比的sparkline视图。based on jquery.sparkline.min.js

composite-sparkline.js

$(".sparkline").each(function(idx){
	var data = _.map(_.range(60*5),function(i){return 5*i+1000*0.5*Math.sin(i*0.1/Math.PI);});
	var data2 = _.map(data,function(r){return r*(Math.random()+2);});
	var allData = data.concat(data2);
	var config = {chartRangeMin:_.min(allData),chartRangeMax:_.max(allData)};
	console.log(config);
	$(this).sparkline(data2,_.extend({width:"100%",height:80,lineColor:"hsla(30,100%,60%,0.6)",fillColor:"transparent"},config));
	$(this).sparkline(data,_.extend({width:"100%",height:80,lineColor:"hsla(200,100%,60%,0.6)",fillColor:"hsla(200,100%,60%,0.2)",composite: true},config));
