<p><img src="http://i.stack.imgur.com/9GWAO.jpg" alt="highchats"></p>

<p>Can the highlighted "green" part be removed?</p>

<p>code:</p>

<pre><code>chart = new Highcharts.StockChart({
    chart: {
        renderTo: renderTo,

    },
    title: {
        text: 'test - ' + title
    },
    zoomType: false,
    subtitle: {
     text: 'some text'
    },
    rangeSelector: {
        selected: 4
    },

    yAxis: {
        labels: {
            formatter: function() {
                return (this.value / 1000000) + "mil";
            }
        },
        plotLines: [{
            value: 0,
            width: 2,
            color: 'silver'
        }]
    },

  credits: {
      enabled:false
  },


        plotOptions: {
        series: {

            marker : {
                enabled : true,
                radius : 3
            }
        }

    },

    },

    series: seriesOptions
});
</code></pre>
