Question

我正在尝试为广告牌图表使用一些自定义点。我可以使用<path>元素，它将被呈现为数据点。

我想做的是使用某些点，这些点可能是svg元素的分组，因此我试图将<g>或<svg>与其中的某些元素一起使用。

据我所见，图表<defs>仅包含g / svg包装器，而g / svg不包含任何元素。

有没有办法使这项工作有效？那么要渲染整个g / svg元素吗？

在下面的示例中，我使用了一个'circle'和'path'元素，并渲染了它们。我还使用了内部带有元素的g和svg，这些元素未呈现

一种方法，看来我可以使用onrendered附加要使用的svg / g的内部元素，尽管这似乎并不复杂，但这可能是一种方法是正确的方法。

svg defs path {
  stroke: black;
  opacity: 0.2;
}

svg defs g rect {
   stroke: black;
}

Answer 1

实现了将摸索节点设置为自定义点的功能。检出https://github.com/naver/billboard.js/issues/562以获得更多详细信息。

通过此更改，只需将分组节点设置为值。

point: {
    pattern: [
        "<g><circle cx='10' cy='10' r='10'></circle><rect x='5' y='5' width='10' height='10'></rect></g>"
    ]
}

如何在billboard.js中使用更复杂的svg作为图表点？
