title: HighCharts: Reduce size of chart
body: <p>Does anyone know how to reduce the size of this pie chart? I am using Lazy High Charts gem.</p>
  
  <pre><code>return LazyHighCharts::HighChart.new('pie') do |f|
        f.chart({:defaultSeriesType=&gt;"pie" , :margin=&gt; [0, 0, 0, 0],  backgroundColor: "#F5F5F5", renderTo: "mediamix#{akid.to_s}"} )
        f.series({:type=&gt; 'pie', :name=&gt; "Count",:data=&gt; data_val, borderWidth: 0})
        f.title({ :text=&gt; nil})
        f.plot_options({:pie=&gt;{:allowPointSelect=&gt;true, :cursor=&gt;"pointer" , dataLabels: {enabled: true}, showInLegend: false}})
      end
  </code></pre>
