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 } ] };
