huanledeniuduzi opened a new issue #10594: echarts2.0自定义图片热力图问题
URL: https://github.com/apache/incubator-echarts/issues/10594
 
 
   请问我用echarts2.0写了一个自定义图片的热力图，数据源位置是点距左边和上边的距离，我想实现自己控制热力图的最大值和最小值，以及如何实现鼠标移到热力点位置时出现该热力点的描述信息？谢谢
   数据格式为：
    ["1881", "2202", 0.2742822625017776, "热力点描述信息"]
   option = {
   		title : {
   			text: ''
   		},
   		series : [
   			{
   				type : 'heatmap',
   				data : heatDatas,
   				hoverable : true,
   				gradientColors: [{
   					offset: 0.2,
   					color: '#36FF02'
   				}, {
   					offset: 0.4,
   					color: '#547CED'
   				}, {
   					offset: 0.6,
   					color: '#EF84ED'
   				}, {
   					offset: 0.8,
   					color: '#DB7300'
   				}, {
   					offset: 1,
   					color: '#FF4D47'
   				}],
   				minAlpha: 0.2,
   				valueScale: 2,
   				opacity: 0.6
   			}
   		]
   	};
