Re: [Trac] Data-based graphics in Trac
the google charts API http://code.google.com/apis/chart/docs/making_charts.html is very nice for externalizing server-side data-driven image generation, so it's worth looking at. Combining a made chart with an image map http://www.w3schools.com/TAGS/tag_map.asp would be trivial, for a sufficiently loose definition of trivial. -- You received this message because you are subscribed to the Google Groups Trac Users group.

JFTR , this wouldn't happen using GViz API since the contents are retrieved from the given URL (not URL-encoded ...). We really want to render locally. But thanks. TracGViz may be suitable for this as well , and there are actually many ways to get there ... one of them (the easiest | straightforward ???) may be to implement Dojo data sources to consume data formatted using GViz wire-protocol .

Now that you are after this I think this could be a great opportunity to add local chart capabilities to TracGViz . This plugin is about representing data using tables, filtering using custom SQL, and transmitting it to remote locations (e.g. user browser) mainly for visualization purposes. I have even thought about the possibility of using it as the foundations to build a replacement for TracReports (but have no time ... :( ...). In any case you should be able to use SVG, matplotlib, GraphViz ... but you could also dump the data directly to the browser and render it using HTML5 canvas (AFAICR this is the way Hg draws the revision graph).

That's not quite right: Raphael is a Javascript framework for drawing svg (vector graphics) directly in the browser, embedded in an HTML document -- *not* HTML5 canvas (bitmaps). http://raphaeljs.com I've been using Raphael and its graphing extension g.raphael in a (non-Trac) project recently, for visualizing datasets from a simulation game and interactively exploring the data relationships. I've been pretty happy using Raphael for this .. but if you're going to go with client-side rendering there's a whole slew of options. One I've been wanting to check out is http://vis.stanford.edu/protovis/ which, at first glance, looks like it's both more high-level and more flexible than most charting frameworks. (g.raphael, by contrast, is quite flexible, but only at a pretty low level; it does the simple things easily, but you have to interact pretty closely with your data and with SVG tags if you want highly customized behavior. Most of the other tools I looked at were rather inflexible.) Server-side rendering of the data (whether to a bitmap or an SVG document) is probably simpler unless you have particular needs for highly interactive interfaces. I've only done client-side data visualizations though ... so I can't offer any advice on choosing between server-side options. -Ethan -- You received this message because you are subscribed to the Google Groups Trac Users group.

Server- vs. client-side rendering is an interesting dichotomy I hadn't considered. My immediate need is for a bar chart with some links out to other parts of Trac. I can easily do that with SVG. But a future project is an interactive Gantt which would work a lot like Microsoft Project's WBS/Gantt view and allow, for example, editing links between tasks. I imagine that level of interactivity requires client-side processing. -- You received this message because you are subscribed to the Google Groups Trac Users group.

Re: [Trac] Data-based graphics in Trac
Quoting Chris Nelson chris.nel...@sixnet.com: But there seem to be a lot of ways to do this. One more: matplotlib. The new version seems to support SVG, but the good thing is, that you can emit PNG and many other formats, if e.g. your browser doesn't support SVG. We use matplotlib in a web application, not based on Trac, but on Django, and it is really nice. -- You received this message because you are subscribed to the Google Groups Trac Users group.
