Re: [time-nuts] What size graphs do people like? (How big is yourscreen?)
So you are saying that SVG can't work because one example of it is broken.
Also, there are other vector formats, like Postscript and PDF.
No. I think my ISP's web server has a simple misconfiguration.
It does work for ps and pdf, at least with my copy of Firefox.
http://www.megapathdsl.net/~hmurray/time-nuts/test/
ps and pdf, at least the way I see them, are not in the same boat as SVG.
SVG is an image format that can easily be included in a html page. ps and
pdf are stand alone. They assume they control the whole setup and are
targeted at paper. Think 8.5x11 or A4.
Yes, if you have a good pdf display program, you can zoom in/out. But I
haven't seen pdf graphs included inside normal html pages.
Again, my knowledge of this area is not-great. I could easily have missed
something.

Hal,
I never tried to use SVG before, but after your messages tonight I
played around with it a bit. I would never have expected it, but I think
you are right about the issue being a server configuration.
I copied your SVG file and got the same results. On my local hard drive
it opens as a graph. I copied it to my own web pages and I also saw it
display as text.
I browsed around and found this SVG picture:
https://upload.wikimedia.org/wikipedia/en/2/22/Heckert_GNU_white.svg
It displays fine at that link. I copied the svg file to my web
directories (hosted by GoDaddy) and there the same file displays as text.
I have a debugging tool add-on on FireFox. I displayed a thing called
'Response Headers' that (I think) come from the server. For the svg link
on my pages I see one field: 'Content-Type: text/plain'. If I do the
same response header display on the wikimedia.org link I see
'Content-Type: image/svg+xml'. So that seems to be what makes it work or
not work.
If you go to: http://validator.w3.org and enter your link into the
address field
(http://www.megapathdsl.net/~hmurray/time-nuts/coax/Front-5ns-800x600.svg)
then click Check, you will get a message that sort of explains the
situation, except I still don't know how to get the server configured
for for svg file => 'Content-Type: image/svg+xml'.
So it seems most browsers are now ready for SVG, but many servers are
not. Maybe someone else can give us more details on what change might be
required. In the mean time it looks like I won't be using any SVG on my
pages either.

I agree that most browsers are now ready for SVG, even when it is
embedded in HTML. So, I'd try to create HTML documents with your SVGs
embedded on them, this way:
Maybe this is a solution for the mime-type mismatch at GoDaddy :-)

I don't use svg either, but the version of apache I have installed
(2.2.19) does have svg listed in the mime types config file.
/usr/local/etc/apache22/mime.types
...
image/prs.pti
image/svg+xml svg svgz
image/t38
...
If your server is apache I think that uncommenting the line and
restarting httpd should be enough. If you have a propriety server you
may need to update something else.
Firefox accessing my server does display the graph correctly.

Here is a random counterexample to the above.

That said. SVG is probably the way to go. But Postscript (EPS) is more
sophisticated in that PS is an executable script that draws an image. This
means you can do conditional branching and computation to for example
replace text with grey blocks if scaled below some limit. SVG is only
descriptive, not executable. SVG is likely good enough for making a graph.
If you are worried about the size of an SVG file you can use a compressed
link on the web page and cut the amount of data sent to maybe 30%

Yes your link is correct. I cut and pasted the wrong one. "EPS" is the
style of postscript that is intended to be embedded.

On both Firefox and MS Internet Explorer, that page expects a 3rd-party
helper to visualise the EPS content.
