What is the crowd's opinion of ZingChart?

From 3.5 billion comments

You're not alone in this opinion.

Websockets: I've not had occasion to use many different implementations, but from what I hear from those who can compare CF's to, say, Grails', is that CF's is much easier to use. And there's no way that would have been in a point release.

The charting update was needed (the old charting stuff was getting long in the tooth), but making it an enterprise-only feature is a joke. You can go buy ZingChart yourself (for far less than a CF upgrade) and it will be easier (aka possible) to update if/when updates are available.

The REST stuff is long overdue, but their implementation leaves a lot to be desired, and shows that they are Java developers, not ColdFusion developers... They really don't grok what kind of code CF developers want to write.

...

And still CFScript is incomplete. SerializeJSON has glaring bugs.

And my biggest complaint of all? The release cycle. At a time when everyone else in the industry is shortening release cycles to 1 year or less, Adobe took their 2 year RC and made it 3+. I've heard rumors that they want to make it shorter, but only time will tell.

Submitting ZingChart for evaluation/discussion. I'm on the team.. so I'm happy to answer any questions at abegin[at]zingchart.com - Andrew (feedback also welcome).

Zing allows you to render in HTML5 Canvas, SVG, Flash or VML.. so you can build interactive charts that work in IE6 and on the iPad and everything in between.

There is plenty of JavaScript librairies that can build a graph out of a csv. Here is an exemple to use one: http://www.zingchart.com/docs/labs/csv-data/

Integrating that in your WordPress site should be easy.

ZingChart team here... you might be interested in trying our library with the React component we developed. We're also available if you have any questions.

Without knowing exactly what went on at FitBit, we can tell that a lot of this dashboarding can be accomplished with a JavaScript charting library.

We're on the ZingChart team, but there are many options for creating these interactive charts and dashboards out there. Here is one big comparison list - http://en.wikipedia.org/wiki/Comparison_of_JavaScript_charting_frameworks

ZingChart, although lesser known, would certainly work for you. The trial is unlimited, it handles huge data sets with ease and there are multiple render options. They have a candle stick chart that you can customize to your heart's content.
