Ok... I had to (require 'ob-gnuplot), but then the example worked fine.
It took a while but I got my own table work as well, more or less (see
below).

Thank you very much!

Very nice overview and reference, thank you very much as well.

I now have one remaining problem: my time values in the second column
contain the name of the time zone - the purpose is to flag the time as
summer or winter time.  Currently I need to remove these indicators from
the table, else plotting fail, gnuplot doesn't understand the data.

Can I tell "ob-gnuplot" to export the table in a different way - how?

The time zone makes a difference when exporting since the generated
data file has a different format: the time fields including the timezone
get wrapped in quotation marks, without time zone they are exported
literally.


Thanks again,

Michael.
