The “Powered by ZingChart” watermark appears when you use the branded, non-licensed version of ZingChart. This version is free and provides full access to the ZingChart library. In using the branded version, however, the watermark must stay visible on all charts created. See our branded licensing agreement for more information.
Only paid license users can remove the ZingChart watermark and branding from their charts. Chat with us (see the bottom-right corner of the page) or email email@example.com to learn more about your licensing options.
