Please help me how to do this.



The issue is because your CSS file can't be loaded from external server . Lightning will block any external callout from client side for security reasons .

You can store the CSS file inside static resource and reference the same in your component .

    Check your console to see if any other issues – Mohith Shrivastava May 11 '16 at 12:26
  • Hello Mohith Now i was getting same message Refused to load the stylesheet 'gstatic.com/charts/44/css/util/util.css' because it violates the following Content Security Policy directive: "style-src 'self' chrome-extension: 'unsafe-inline'". – Piyush Kumar May 11 '16 at 12:54
  • So yes your CSS file is again referencing from external source. Download that and keep all in static resource – Mohith Shrivastava May 11 '16 at 12:56
  • I download it use this css file through static resource but i still get same error message. – Piyush Kumar May 11 '16 at 14:11
