图例项的legend icon。

ECharts 提供的标记类型有 'circle', 'rect', 'roundRect', 'triangle', 'diamond', 'pin', 'arrow', 'none'

也可以通过 'image://url' 设置为图片,其中 URL 为图片的链接,或者 dataURI。

URL 为图片链接例如:

'image://http://xxx.xxx.xxx/a/b.png'

URL 为 dataURI 例如:

'image://data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOyDZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7////wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQAosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIgUhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB0UjIQA7'

可以通过 'path://' 将图标设置为任意的矢量路径。这种方式相比于使用图片的方式,不用担心因为缩放而产生锯齿或模糊,而且可以设置为任意颜色。路径图形会自适应调整为合适的大小。路径的格式参见 SVG PathData。可以从 Adobe Illustrator 等工具编辑导出。

例如:

'path://M30.9,53.2C16.8,53.2,5.3,41.7,5.3,27.6S16.8,2,30.9,2C45,2,56.4,13.5,56.4,27.6S45,53.2,30.9,53.2z M30.9,3.5C17.6,3.5,6.8,14.4,6.8,27.6c0,13.3,10.8,24.1,24.101,24.1C44.2,51.7,55,40.9,55,27.6C54.9,14.4,44.1,3.5,30.9,3.5z M36.9,35.8c0,0.601-0.4,1-0.9,1h-1.3c-0.5,0-0.9-0.399-0.9-1V19.5c0-0.6,0.4-1,0.9-1H36c0.5,0,0.9,0.4,0.9,1V35.8z M27.8,35.8 c0,0.601-0.4,1-0.9,1h-1.3c-0.5,0-0.9-0.399-0.9-1V19.5c0-0.6,0.4-1,0.9-1H27c0.5,0,0.9,0.4,0.9,1L27.8,35.8L27.8,35.8z'
