title: Setting Highcharts piechart chartDefaults from calling jsx file in React
body: <p>I am using the following syntax to render a Highcharts PieChart.</p>
  
  <pre><code>var ContainingClass = React.createClass({
    render: function() {
      return (
          &lt;PieChart
              title={this.props.title}
              series={this.props.series}
          /&gt;
      );
    },
  });
  </code></pre>
  
  <p>This works well, but I need to overwrite the <code>tooltip</code> field in <code>PieChart</code>.  What can I change in <code>ContainingClass</code> to make this happen?  </p>
  
  <p>Edit: Here is a sample fiddle with <code>PieChart</code> - <a href="http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/pie-basic/" rel="nofollow">http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/pie-basic/</a> I know that I need to set the tooltip field and could do it in plain javascript or jquery. I don't know how to pass my desired <code>tooltip</code> value from <code>ContainingClass</code> in React.</p>
