title: ECharts: change line color
body: <p>This is my EChart init code:</p>
  
  <pre><code>var option = {
  tooltip : {
        trigger: 'axis'
    },
    calculable : true,
    xAxis : [
        {
            type : 'category',
            boundaryGap : false,
            data : cat
        }
    ],
    yAxis : [
        {
            type : 'value'
        }
    ],
    series : [
        {
            name:'Series 1',
            type:'line',
            smooth:true,
            itemStyle: {normal: {areaStyle: {type: 'default'}}},
            data:val
        }
    ]
  };
  </code></pre>
  
  <p>The line appears with area (correct) and colored in red (I think by default, I haven't added anything to my code). How can I change the color of the chart's line? </p>
  
  <p>I've tried with </p>
  
  <pre><code>itemStyle: {normal: {areaStyle: {type: 'default'}}, color: '#d5ceeb'},
  </code></pre>
  
  <p>but it doesn't work. </p>
