I'll *try* to have a look. Hi Andy, thanks for the hint. I’ll *try* to have a look.

It's fast, requires 2*m+3 markers (for m percentiles) and tends to an accurate approximation quickly.

I've always believed that data is nothing without (sexy) visualization. @Dag Thanks, fixed that. I'veuploaded two additional files: (<a href="/files/IntervalPercentileChartImage.java" rel="nofollow">IntervalPercentileChartImage.java</a> and <a href="/files/GoogleChartModel.java" rel="nofollow">GoogleChartModel.java</a>) While these files require some effort to make them compile, they should give a very good start to generate Google Chart URLs from PecentileCounters. That's the extra effort you could have avoided with a small donation - you'd be surprised what people do for beer :D (After doing this yourself, I'd be very happy to upload the changed/working version though) @Markus Thanks!

You forgot to let PercentileCounter implement Iterable to make it compile though. :) Go a class for generating the GChart url too? Great stuff!
