GFwer opened a new issue #9014: 使用Safari在svg渲染模式下，rgba渐变的透明度值失效 URL: https://github.com/apache/incubator-echarts/issues/9014 <!-- 为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。 --> ### One-line summary [问题简述] 使用Safari，在透明度设置值 ``` new echarts.graphic.LinearGradient( 0, 0, 0, 1, [ { offset: 0, color: 'rgba(172,90,255,0.2)' }, { offset: 1, color: 'rgba(172,90,255,0)' } ] ) ``` 之后，无论是设置areaStyle还是直接设置color，在Safari上结果都好像是直接忽略的透明度的值，同时Chrome/FireFox 上都可以正常显示 ### Version & Environment [版本及环境] + ECharts version [ECharts 版本]:4.1.0 + Browser version [浏览器类型和版本]:Safari 11/Safari 12，Chrome 69 , FireFox 61 + OS Version [操作系统类型和版本]:MacOs 10.13.6/MacOs 10.14 Beta ### Expected behaviour [期望结果] 能够正常显示透明度 ### ECharts option [ECharts配置项] <!-- Copy and paste your 'echarts option' here. --> <!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 option。如何得到能运行的 option 参见上方的 guidelines for contributing] --> ```javascript option = { "title": { "text": "" }, "tooltip": { "trigger": "axis" }, "legend": { "data": [], "show": false }, "grid": { "left": 5, "right": 15, "bottom": "2%", "top": "4%", "containLabel": true, "show": true, "backgroundColor": "transparent" }, "xAxis": { "type": "category", "boundaryGap": false, "data": [ "0:00", "0:30", "1:00", "1:30", "2:00", "2:30", "3:00", "3:30", "4:00", "4:30", "5:00", "5:30", "6:00", "6:30", "7:00", "7:30", "8:00", "8:30", "9:00", "9:30", "10:00", "10:30", "11:00", "11:30", "12:00", "12:30", "13:00" ], "splitLine": { "show": false }, "axisTick": { "show": false }, "axisLine": { "show": false }, "axisLabel": { "fontSize": 10 } }, "yAxis": { "type": "value", "min": 0, "axisTick": { "show": false }, "axisLabel": { "fontSize": 10 }, "axisLine": { "show": false }, "splitLine": { "show": true }, "interval": 69211 }, "series": [ { "name": "1", "type": "line", "smooth": true, "itemStyle": { "normal": { "opacity": 0 } }, "lineStyle": { "normal": { "width": 1.5, "color": "#AC5AFF" } }, "z": 0, "areaStyle": { "normal": { "color": new echarts.graphic.LinearGradient( 0, 0, 0, 1, [ { offset: 0, color: 'rgba(172,90,255,0.2)' }, { offset: 1, color: 'rgba(172,90,255,0)' } ] ) } }, "data": [ 31574, 164657, 276844, 101562, 112015, 92247, 76087, 75194, 58138, 57983, 70396, 90285, 94566, 91314, 114043, 91601, 73448, 45801, 76783, 257652, 264912, 110699, 144759, 117858, 83102, 71152, 62269 ] } ], "animationEasing": "circularOut" } ``` ### Other comments [其他信息] <!-- For example: Screenshot or Online demo --> <!-- [例如，截图或线上实例 (JSFiddle/JSBin/Codepen)] --> 附上JSFiddle： https://jsfiddle.net/vepj821g/18/
