tabindex="-1">图形的形状</h3>\n<p>图形（symbol）指的是散点图中数据“点”的形状。有三类图形可选，一种是 ECharts 内置形状，第二种是图片，第三种是 SVG 的路径。</p>\n<p>ECharts 内置形状包括：圆形、矩形、圆角矩形、三角形、菱形、大头针形、箭头形，分别对应<code>\'circle\'</code>、<code>\'rect\'</code>、<code>\'roundRect\'</code>、<code>\'triangle\'</code>、<code>\'diamond\'</code>、<code>\'pin\'</code>、<code>\'arrow\'</code>。使用内置形状时，只要将 <code>symbol</code> 属性指定为形状名称对应的字符串即可。</p>\n<p>如果想要将图形指定为任意的图片，以 <code>\'image://\'</code> 开头，后面跟图片的绝对或相对地址。形如：<code>\'image://http://example.com/xxx.png\'</code> 或 <code>\'image://./xxx.png\'</code>。</p>\n<p>除此之外，还支持 SVG 的路径作为矢量图形，将 <code>symbol</code> 设置为以 <code>\'path://\'</code> 开头的 SVG 路径即可。使用矢量图形的好处是，图片不会因为缩放而产生锯齿或模糊，并且通常而言比图片形式的文件大小更小。路径的查看方法为，打开一个 <code>SVG</code> 文件，找到形如 <code>&lt;path d=&quot;M… L…&quot;&gt;&lt;/path&gt;</code> 的路径，将 <code>d</code> 的值添加在 <code>\'path://\'</code> 后即可。</p>\n<p>下面，我们展示一个将图形设置为矢量爱心形状的方式。</p>\n<p>首先，我们需要一个爱心的 SVG 文件，可以使用矢量编辑软件绘制，或者从网上下载到相关资源。其内容如下：</p>\n<md-code-block lang="xml"
