Ranked in these QuestionsQuestion Ranking
Pro Robust API
Pro Tons of styling options
You can get extremely granular with the styling (which is very CSS-like). You can customize pretty much any aspect of a chart, so they can match your application or website perfectly.
Pro Easy to try
ZingChart hosts the full version of the library for evaluation on their CDN for you to try in just a matter of minutes.
Pro Angular wrapper
Pro Free branded version
There is a free version available, however it's branded. Licenses start at $249.
Pro jQuery wrapper
ZingChart has a well-built and excellently documented jQuery wrapper, making it easier to integrate ZingChart into your jQuery code.
Pro Handles large data sets without bogging down
Pro Extremely simple to implement.
To get started is extremely simple. It has a low learning curve.
Pro Seems to be quite stable
Even the most complicated GUIs are bug-free most of the time.
Pro Great support from the webix team
The company behind webix is really quick in answering any questions you have on their forum or via email.
Pro Webix Jet
The webix Jet library adds all the required features for SPA development (routing, template loading, ...)
Pro A lot of widgets
Webix is one of the most extensive UI component libraries, second only to Sencha ExtJS. Not only considering the number of widgets, but also the API methods for manipulating these widgets.
Con Not open source
Con The free version inserts a watermark on all charts
Either their watermark is on all the charts or you have to pay expensive license fees.
Con Not very popular
Not really a reason to not recommend it. But it has still a small user base. It deserves a lot more attention.
Con Not modular
The library is not modular (except for some additional more complex widgets). If you only need a few widgets, you still need to include the entire library.
Con Commercial license
It's not free for commercial applications.
