ZingChart is not open-source. We are a closed-source, proprietary software product specializing exclusively in charts. We don’t share our source code with the public (a mandatory requirement for some clients), offer professional-level support, and continually update and improve our library.
For questions about our library, contact our support team at firstname.lastname@example.org. We’re also available on chat (see the bottom-right corner of the page), and are generally online Monday through Friday, 8 a.m. to 5 p.m., Pacific time.
