I love very much your plugin and also chart.js.
But i think that for a better user experience some additions are needed.
I'm talking about that on a financial plugin users should be able to click on the graph and draw slanted lines, equidistant channels and linear regressions from point to point.
That's a very important think.
Other than that, congratulations and great job.
It's a real spectacle to see and the time saved is a lot.
Thanks
