ZingChart: What do I receive with a paid ZingChart license?
See the Pricing page for a breakdown of the license types and support hours we offer. License keys are generally distributed by domain. (Users that require domain anonymity would need to buy an Enterprise or Universal license.) That means that all charts that appear under that domain will be unbranded (no watermark or context menu item). Licensed users also receive higher priority on support, and they provide us the insight and means to continue improving and developing our charting library.
