Re: [time-nuts] What size graphs do people like? (How big is yourscreen?)
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. -Rex On 8/7/2012 11:57 PM, Hal Murray wrote: albertson.ch...@gmail.com said: So you are saying that SVG can't work because one example of it is broken.

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.

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.

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.
