        data: ['A', 'B', 'C']
    }
};

// 使用刚指定的配置项和数据显示图表。
        myChart.setOption(option);

    </script>
</body>
</html>

步骤一:引入echarts相关JS库

<script src="echarts.js"></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/extension/dataTool.min.js" type="text/javascript" charset="utf-8" async defer></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/echarts.simple.min.js" type="text/javascript" charset="utf-8" async defer></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/echarts.js" type="text/javascript" charset="utf-8" async defer></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/echarts.common.min.js" type="text/javascript" charset="utf-8" async defer></script>

步骤二:

下边JS中加入这句话:var myChart = echarts.init(document.getElementById('main'));

下边JS中末尾加入这句话:

// 使用刚指定的配置项和数据显示图表。
myChart.setOption(option);

中间就是demo中的JS示例代码了;
