echarts 热力图heatmap

1、配置data热力图主要通过颜色去表现数值的大小,必须要配合visualMap组件使用。可以应用在直角坐标系以及地理坐标系上直角坐标系上必须要使用两个类目轴。当坐标轴为直接坐标轴时,根据x、y轴每项数据相交形成的网格来进行定位,如x:['aa','bb'],y:['cc','dd'],(0,0)表示第一排第一个data:[[x,y,label内容,...],...]2、配置seriesvisualMap:{...},series:[{type:'heatmap',}]

效果图:

代码示例:

var hours = ['12a', '1a', '2a', '3a', '4a', '5a', '6a','7a', '8a', '9a','10a','11a','12p', '1p', '2p', '3p', '4p', '5p','6p', '7p', '8p', '9p', '10p', '11p'];
