svg 中的剪辑路径和变换组合

Question

请参考以下组中的剪辑路径。

<g id="container_svg_SeriesCollection" clip-path="url(#container_svg_ChartAreaClipRect)"><defs>
<clipPath id="container_svg_ChartAreaClipRect">
<rect id="container_svg_ChartAreaClipRect" x="128.8" y="20" width="651.2" height="415" fill="white" stroke-width="1" stroke="Gray"/>
</clipPath>
</defs>
<g id="container_svg_symbolGroup_0" transform="translate(128.8,435)" clip-path="url(#container_svg_ChartAreaClipRect)">
<circle id="container_svg_circlesymbol_3_0" cx="86.8" cy="-25.875" r="7.0710678118654755" fill="url(#container_svg_symbol0Gradient)" stroke-width="1" stroke="Gray"/><circle id="container_svg_circlesymbol_4_0" cx="108.5" cy="-155.25" r="7.0710678118654755" fill="url(#container_svg_symbol0Gradient)" stroke-width="1" stroke="Gray"/></g>
</g>
</g>

组 ID -> “container_svg_symbolGroup1_0（即圆圈符号）在我删除剪辑路径时不可见，图表中可见。

有什么问题？为什么在某些情况下 transform 和 clip-path 不能一起工作？

如何在上面的剪辑路径中显示圆形符号？

Answer 1

您有嵌套的剪辑路径，重复使用相同的两次。 删除内部剪辑路径，它可以工作。

（包装在 SVG 文档中）：

<svg version="1.1"
     baseProfile="full"
     xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     xmlns:ev="http://www.w3.org/2001/xml-events">
    <g id="container_svg_SeriesCollection" clip-path="url(#container_svg_ChartAreaClipRect)">
        <defs>
            <clipPath id="container_svg_ChartAreaClipRect">
                <rect id="container_svg_ChartAreaClipRect" x="128.8" y="20" width="651.2" height="415" fill="white" stroke-width="1" stroke="Gray"/>
            </clipPath>
        </defs>
        <g id="container_svg_symbolGroup_0" transform="translate(128.8,435)">
            <circle id="container_svg_circlesymbol_3_0" cx="86.8" cy="-25.875" r="7.0710678118654755" fill="url(#container_svg_symbol0Gradient)" stroke-width="1" stroke="Gray"/>
            <circle id="container_svg_circlesymbol_4_0" cx="108.5" cy="-155.25" r="7.0710678118654755" fill="url(#container_svg_symbol0Gradient)" stroke-width="1" stroke="Gray"/>
        </g>
    </g>
</svg>

另外，我会从 clipPath 内的矩形中删除 id="container_svg_ChartAreaClipRect"

我自己找到了解决方案。请参考以下修改后的 SVG。

问题是父组和子组中使用了多个相同的剪辑路径。

我已将子组剪辑路径修改为其他剪辑路径，然后它工作正常。

因此无需为父组和子组设置相同的剪辑路径。如果要为子组设置剪辑路径意味着剪辑路径边界将小于父剪辑路径。

谢谢，
