Is this bounty still open?
http://www.devtome.com/doku.php?id=devcoin_bounty_now#devcoin_usd_chartThe dvc/usd chart.
I've coded up a webserver that gets the averages from a few different places, but I couldn't find a long term history of DVC.
The chart is here:
http://dvcusdchart.blisteringdevelopers.comIt's filling up with data as I just reset it after testing, and it'll log and show data indefinitely. If people want more options etc, say what you like and I'll code it in. I'll make a few more tweaks to make it clearer what's what, but it's up and running now in any case.
EDIT: Obviously it looks a bit silly now but that's because data's just started collecting...it should fill out soon enough

I think a legend would be helpful (line vs bars, solid bars vs empty bars. I'm assuming that has to do with the fact that you're collating several averages). Is the 15 minute limit just because the chart just got put up? I think it'd be nice to see a longer term chart (you can get a long term chart from dvc to btc at vircurex, but not straight to USD).
Thanks for putting it together!
