Thanks for the above, so its just for debugging back to the source and
I could switch it off, but if I am debugging perhaps I can find it
somewhere!
I suppose it did not matter for the Pi's browser which did not seem to
have a console and the code was assumed to "just work"!

Thanks Shane, I found that typo by the time I read your reply!

I am thinking of giving up on this soon as I think I've solved my
problem in the loft that I was going to use it for, but i do like like
being beaten and I have learnt quit a lot!

Will try a similar example on Dygraph site from a weather station
project to see if that works with their temperatures.csv file:

That dygraphs example should work. The only thing is that the cron job
you're using from the beer example is outputting the date into the file
in a format that dygraphs can't use. That's the reason for the "new
Date" call in the Javascript that converts the date from the file
(YYYYMMDDHHMMSS into HH:MM:SS MM/DD/YYYY).

I don't know why the beer example does it like that. If you change the
cron job to run the date command like this:

date "+%T %m/%d/%Y"

then you should be able to use that date directly in dygraphs without
messing around with it. In fact, this:

date "+%T %F"

would probably work too and has the advantage of not using US date format!

Feeling a bit off it today etc, so no I won't be there this afternoon.
A Christmas meal would have been nice though, but well I am probably
going to have quite a few meals out next year any way.
