I tried running emacs in a shell window with no initialization file, and t.org <http://t.org/> *did* export HTML, and PDF (although I *still* don’t get the graph).

So yes, I guess there’s something in my init file that’s messing this up.

Chances of finding it in my lifetime: near zero.

Meanwhile, I have discovered a Google charting function which gives me an annotated time series graph that comes very close to what I need. Also, I’ve had no problems exporting many other documents to HTML and/or PDF. So I’m afraid solving this has dropped on my priority list.

Thank you all for your help,
