为什么SVG图在生成的PDF中的行为与在浏览器中的不同？

Question

我想根据一些先前计算的数据生成一个图表。该图表应该在PDF上以及更多信息。Apache Fop 2.0用于生成PDF，但生成的PDF看起来与浏览器中的SVG不同。

• SVG：
PDF

SVG图形在所有测试的浏览器（IE、Chrome、Firefox）中看起来都一样。我已经尝试将SVG代码插入fo:instream foreign object标记中，或者将单独的文件包含在fo:external graphic中，但两种变体的行为相同。我还尝试将SVG图像导出为其他格式，如PNG，但导出的图像看起来也像PDF版本。

我必须更改哪些内容才能使 SVG 图形在浏览器和生成的 PDF 中具有相同的行为？

这是生成的. svg：
