automated chart generation with kchart ?

Hi,

I'd like to use kchart to generate a chart (as an image -
png, jpg, whatever) 
in an automated way (e.g. from a cron job, like gnuplot
can). Generating the 
input file is not really a problem, it's just exporting an
image. Ideally I 
could invoke the 'export' function from dcop, but I
couldn't find it in the 
available interfaces. Am I missing anything ? (Googling
around didn't help)

(please CC me in the reply as I'm not subscribed, but I'll
watch the archives 
anyway).

Thanks,

-- 
Guillaume.

Hi,

Someone at the Linuxwochen in Vienna asked the exact same
thing.

AFAIK you can use DCOP with KOffice 1.5 to do
"some" of the things you need. 
Without knowing all the details I remember that some of the
dcop calls 
(especially those opening dialogs) were blocking calls, so
the use is 
somewhat limited.

This information _might_ be outdated, maybe it's all
supported and fine 
already.

If not, a new scripting interface is currently taking over
the whole world... 
ehm... koffice. Its called Kross, and supports multiple
scripting languages 
(in particular Python and Ruby). It's already available for
some components 
in the 1.5 release, but not yet for KChart (again, AFAIK).

Kross is certainly meant to be available throughout all
KOffice with the 2.0 
release as a sophisticated (= usable for real work)
scripting interface.

Others might know more details than I.

I know that saying "use B" when you asked about
A, is not a real solution, but 
maybe you can try kst (http://kst.kde.org/). It's a
very nice data 
visualization application, and has exactly this feature.

Well, all I want is to generate charts in an automated way.
If kst can do bar 
charts, I don't mind using it instead of kchart, even if it
looks a bit like 
using a hammer to break eggs . Thanks
for the tip.

Well, if you egg is like this: http://tinyurl.com/js7bt

Seriously, I think those blocking DCOP (or alter D-BUS)
calls should
be modified/extended to allow non-interactive handling, i.e.
without
any dialogs at all.
