I'm kind of confused about the "group_by_day" type methods... where do those come from? I guess the app has to code them?

There you go: https://github.com/ankane/groupdate

#13Assuming the data for the graph shown is the dots, then the lines between them should be straight, not curved, because othrwise the graph is pretending to have higher accuracy than it actually has, which is a lie.

Those are from groupdate. https://github.com/ankane/groupdate

#15Very cool, but the site examples broke on my Android 2.3.5 browser - " Cannot set property 'overflow' of null"

Looks like a possible bug with Google Charts http://stackoverflow.com/questions/15195808/cannot-set-prope...

#17This looks nice, but most of the hard work is done elsewhere.
https://github.com/ankane/groupdate (by the same author) makes it simple to output the right JSON grouped by date (awesome!)
Highcharts/Google charts make it simple to turn json into JS graphs.
This library provides glue so you don't have to read the highchart docs. Might save some people some time, I guess...

#18The ruby wrapper lib around the JS is dead simple. Could be ported to any language with ease. Very nice work! https://github.com/ankane/chartkick/blob/master/lib/chartkic...
Thanks! I started out heavy on the Ruby side but moved most logic to the JS to make AJAX charts dead simple to implement. (render :json => chart_data)
The ruby wrapping lib supports AJAX out of the box by passing a URL or route path to the helper and returning JSON from that endpoint.

#20Nice, going to try this.
I particularly like the groupdate concept, and might send you a pull request adding 2.X support, if that fits in line with the project goals. I should have rolled my own years ago rather than repeating the same code at 100 places.
