【问题描述】：
我想根据一些先前计算的数据生成图表。该图应与更多信息一起在 PDF 上。 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 图形在所有经过测试的浏览器（IE、Chrome、Firefox）中看起来都一样。我已经尝试将 SVG 代码插入到 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 图像导出为另一种格式，例如 PNG，但导出的图像看起来也像 PDF 版本。
我必须进行哪些更改才能使 SVG 图形在浏览器和生成的 PDF 中的行为相同？
这是生成的.svg：
