Please download the commercial version from My Account Page. Once downloaded, replacing trial version of the script with commercial version (canvasjs.min.js incase of Chart & canvasjs.stock.min.js incase of StockChart) should work fine. We recommend you to clear the browser cache and try refreshing the page after replacing the script.
