Why does the SVG diagram behave differently in the generated PDF than in the browser?

Question

I want to generate a diagram based on some previously calculated data. The diagram should be on a PDF along with further information. Apache Fop 2.0 is used for PDF generation but the generated PDF looks different than the SVG in the browser.

• SVG:
• PDF

The SVG graphic looks the same in all tested browsers (IE, Chrome, Firefox). I already tried inserting the SVG-code inside a fo:instream-foreign-object tag or include the seperate file with fo:external-graphic but both variants behave the same. I also tried to export the SVG image to another format such as PNG but the exported image looks like the PDF-version too.

What do I have to change so that the SVG graphic behaves the same in the browser and the generated PDF?

This is the generated .svg:

Answer 1

I solved the problen using the attributes x and y instead of dx and dy on the text elements.
