  See this example: https://jsfiddle.net/29dvpbyg/
  
  If you change the symbolSize from 1 to 0, then the itemFormatter will no longer work. We need to format/style the line chart without symbols. Can you please help fix this? Thanks.

  Hi Yifan,

  We have forwarded a bug report to the dev team with internal tracking id 417418. We will update you as soon as this issue is fixed.
  
  In the meantime, you can hide the symbols using CSS. Add a CSS class to the series by using the cssClass property and set the display of the symbols inside this class to none. Please refer to the code snippet and the sample below:

  In JS;

  series: [
              {
                binding: "downloads",
                name: "Downloads",
                chartType: "LineSymbols",
                symbolSize: 1,
                cssClass: 'hide-symbols'
              }
  ],
  

  In CSS:

  .wj-series-group .hide-symbols ellipse {
          display: none;
  }

  Regards,
  
  Ashwin

  Hi Yifan,

  The issue has been fixed in the latest nightly build of wijmo. You may download the build from the link below and verify it at your end. We will notify you as soon as the next stable build is released.

  PS: Nightly builds have not passed through the QA cycles as all of our release builds do. Therefore, they are not suitable in a production environment.
