Raphael JS seems a nice thing to get started, so I'll probably use it and create some kind of an SVG overlay and maybe move to pure HTML at some later point.

[Wikitech-l] JSGantt inside wiki articles
Hi. I faintly remember someone mentioned Gantt diagrams/charts here so here it is: http://www.mediawiki.org/wiki/Extension:JSWikiGantt I must warn you that if you want to look at the code, please close your eyes when you look at jsgantt.js ;-). This must have been a fun project some years ago (there are some really interesting concepts there), but is rather hard in modifying e.g. to allow more then one diagram per page. I'll probably rewrite this someday. I was thinking about either rendering this to SVG or on canvas rather then plain HTML. Any thoughts on that? We use this extension at work to plan/visualize small development sprints by exporting tasks from Flyspray to Gantt XML. This is a bit specific as Flyspray doesn't really have time interval field but I could probably share this code if anyone wanted. And here is an extension that uses Gantt for something a bit different: http://www.mediawiki.org/wiki/Extension:JobSchEd We use this to build something that on might call an out of office schedule. Technically this extension is actually just a JavaScript that gets build dynamically from JS modules by PHP and included in the header. Could probably be used more generally, but as RL is now in 1.17 then this is probably a bit less useful then it was.

I'll probably rewrite this someday. I was thinking about either rendering this to SVG or on canvas rather then plain HTML. Any thoughts on that? I'd probably recommend using SVG as an output format here; in theory the existing support in MediaWiki for rasterizing SVG to PNG could be reused if desired to provide compatibility with older browsers, but more generally SVG lets you have a 'fixed' output format that's device-independent (think of zooming, high-resolution displays, and print output). Also if you add interactivity or clickable components later, that's easier to do in SVG than canvas (where you'd have to manually handle all events, detection of what's being clicked on, etc -- same issues go there with PNG rasterization of SVG, as you'd need to produce an image map or something) -- brion There's also the technique Raphael JS uses. -- ~Daniel Friesen (Dantman, Nadir-Seen-Fire) [http://daniel.friesen.name] ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
