    In This Topic

    In this topic you will add a simple JavaScript function in your source page and apply the JavaScript function name to the Hint object.

    1. Add the following JavaScript function to your source page:

      To write code in Source View

      <script type="text/javascript">
      function hint() {
      return 'x:' + this.x + ',y:' + this.y + ",y1:" + this.data.y1;
      }
      </script>
    2. In design view right-click on the C1BubbleChart and select Properties to open C1BubbleChart's Properties window.
    3. Expand Hint->Content and set the Function property to Hint. This will apply the JavaScript function to the chart tooltip.
    4. Expand ChartLabel and set the ChartLabelFormatString property to c2.
