The branded version is mostly used by organizations and developers that want to evaluate the product and make sure it is an appropriate fit before buying a license. Any user can use the free, branded version so long as they adhere to our branded licensing agreement. This means that users agree not to remove, hide, or reduce the visibility of the ZingChart watermark and context menu item. You can freely display your charts, but the watermark must remain visible on all charts created.
Once you’ve determined that ZingChart is the charting library you want to use, you can email our sales team at firstname.lastname@example.org or chat with us (see bottom-right corner of the page) to buy a license. With a license, all ZingChart branding is removed.
