Thanks again, Peter. That does help. I opened a bug in Apache’s JIRA before
your first response. I’ll add this info there as a comment. If the maintainers
decide to improve the handling of that, then great. But I’ll also see about
opening a defect against XChart.

Subject: Re: Batik cannot render bar charts generated by XChart
Alright I might have found something.
In your 'bar.svg', line 92 has:
<path d="M531.1467011718751,517.4706589889436
L658.3522441406251,517.4706589889436 L658.3522441406251,536.894375
L531.1467011718751,536.894375 Z L-1.7976931348623157E308,536.894375 Z"
style="fill:rgb(0,115,157);stroke:none;"/>
The path ends with "Z L...,... Z" which I think is not great: Z closes
the path and then draws one more Line and then closes the path again.
However Batik is OK with that, the actual problem is the x-coord of
that last line which is -1.7976931348623157E308 i.e. a very large
negative number.
I have made this minimal SVG which Batik also renders as a completely
black image. Edge browser shows a blue square.
<svg height="750px" version="1.1" viewBox="0 0 700 750" width="700px"
x="0px" y="0px" xmlns="http://www.w3.org/2000/svg ">
<path d="M100,100 H600 V600 H100 Z L-1e308,0 Z"
style="fill:rgb(0,115,157);stroke:none;"/>
</svg>
I don't know what the SVG spec says about the allowed range of
numbers, so maybe this is invalid SVG, but it seems to me that Batik
could handle this better.
Hope that helps
Peter
