Web services are a convenient, nearly universal, scheme to communicate 
between boxes.  It's not always in the context of a traditional fat 
server/thin client sort of model.


In fact, I'd say that the client end (the web browser) typically has 
more computing and display horsepower (on a per connection basis) than 
the server in most cases.  Even a fairly big server serving 100s of 
pages per second to iPhone type clients has a more horsepower on the 
receiving end than the sending end.

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

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:

!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.1//EN
http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd; 
html
  head
titleSVG file/title
  /head
  body
svg xmlns=http://www.w3.org/2000/svg; version=1.1
  circle cx=100 cy=50 r=40 fill=red/ 
/svg
  /body
/html

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.

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%

Hal,

As my minimum screen size is 1024 x 600 (on a netbook PC) I would prefer 800 
x 600, although with the browser title and address bars, and the tabs for 
the windows, perhaps 500 pixels high would be better, and perhaps 1000 
pixels wide.  It might also be worth considering that the aspect ratio of 
displays these days is more often 16:10 (or even 16:9), so a 4:3 aspect 
ratio graph may not be making the best use of the screen area.


My browser is not normally run maximised on my PCs with a 1600 pixel wide 
display, so the 1200 wide would still exceed the window width.  I do like 
the idea of linking to a full resolution image, where the actual size is 
appropriate for the precision of the data being viewed.


Magnus - your GNUPLOT is very nice!  But the mouse tracking doesn't work on 
the iPad, or on an Android phone.


Cheers,
David

Re: [time-nuts] What size graphs do people like? (How big is yourscreen?)

2012-08-06 Thread DaveH
The screen sizes were the maximum resolutions of the older display
technology.

640*480 was the original VGA and the 800*600 was the upgraded XVGA.

Website images are generally 640*480 range with the option to click for full
size.

Depending on the software being used, there may be multiple columns on the
page and a larger image will be clipped. Also, many people __still__ do not
enjoy full bandwidth for their internet connections (I am one of these poor
sods) and a full-size image is not polite as it takes a large chunk of
bandwidth to download before the person can see if it is of interest to
them.

Depends. Sometimes there is a lot of data that lines up on the same row

There is no right here. Just different extremes.
