SetOption 多次赋值echarts 折线配置项内容和展示

Echart 会报 ”Cannot read property 'axesInfo' of null”错误，请问如何解决

      option = {
    title: {
        text: 'Awesome Chart'
    },
    xAxis: {
        data: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']
    },
    yAxis: {},
    series: [{
        type: 'line',
        data: [21, 182, 191, 234, 290, 330, 310]
    }]
};

var data1 = [212, 102, 191, 204, 290, 300, 310]
var option1 = option
option1.series[0].data = data1;
myChart.clear();
myChart.setOption(option1, true, true);
