I guess I will just have to not display it with rss - or I will instead make them images. Thanks for the links, I've looked at Google Charts API before, but haven't really used it yet. I'll check out the open flash charts too. Thanks Jason: it should work now, sorry - I had misplaced the javascript file. Thanks for the links, I'll definitely check them out. Have either of you used these for stock charts? WSW: thanks - I know, I’m not sure what to do with the feed reader situation.

I may switch to using that (vs Google Charts API) on a project of mine. After a quick look-see that Open Flash Chart product is really slick.

Sounds like a neat plugin idea. I'll have to check out the open-flash-chart link above. I've also had some success with the Google Charts API. This php class wrapper helped me some: http://code.google.com/p/gchartphp/ Scaling issues were a bitch though. I'm not sure if that class is doing it correctly 100% of the time... or maybe I was confused about things. But I disabled their autoscaling and scaled the point plots myself before sending them to the class. JPGraph is another nice PHP solution: http://www.aditus.nu/jpgraph/ I've used this on some sites running OSCommerce. I didn't have to install it or set it up though, so I can't comment on how hard/easy that is. Good luck. I’m not seeing your sparkline up there in Firefox.

That sounds like a good idea, would it be open source? Would the script just dynamically query the last x days closing price for a given stock similar to this: [spark][type line][size 14,60][series 4,5.12,9,22,17.1,-21,18,5,13,30,24,38,24,26][dot 7,50,5,green][/spark] Where series would be dynamically generated via php. Another easy to charting libs I like to use are: Open Flash Charts: http://teethgrinder.co.uk/open-flash-chart/ and the Google Charts API You will need to deal with the problem of sparklines not being displayed in feed readers.
