Google Chart API - Google Finance Charts

I've been trying to create a chart that looks similar to Google's Finance Charts. I've gotten almost everything I want with the Annotated Time Line Chart, except I can't seem to figure out how to incorporate the volume information they have at the bottom of the charts. 开发者_如何转开发 I was wondering if anybody knew how to do this or where to look, I've been all around their API but can't seem to find it.

Someone, a real live person - not on Stack, suggested this: http://www.humblesoftware.com/finance/index

Going with that as the answer.

IMO this chart looks nearly identical to the original Google Finance chart and is also maintained by Google. It's also a part of the Google charts library wich is pretty awesome by itself.

Try using this clone instead?

The Annotated Time Line Chart doesn't include the bar graphing facility along the bottom which Google Finance has - I imagine they have an internal API set that isn't exposed to the external world.
