微信小程序 echarts在page外怎么重新渲染呢？

Question

这个initChart是在page外的，在page内查询到的结果要怎么赋值给initChart的source呢？

function initChart(canvas, width, height) {
    const chart = echarts.init(canvas, null, {
        width: width,
        height: height
    });
    canvas.setChart(chart);

    var option = {
        legend: {},
        tooltip: {},
        dataset: {
            source: [
                ['轮印', '2015', '2016', '2017'],
                ['平印', 43.3, 85.8, 93.7],
                ['骑马', 83.1, 73.4, 55.1],
                ['胶装', 86.4, 65.2, 82.5],
                ['折页', 72.4, 53.9, 39.1],
                ['打包', 72.4, 53.9, 39.1],
                ['没了', 72.4, 53.9, 39.1]
            ]
        },
        xAxis: {
            type: 'category'
        },
        yAxis: {},
        // Declare several bar series, each will be mapped
        // to a column of dataset.source by default.
        series: [{
            type: 'bar'
        }, {
            type: 'bar'
        }, {
            type: 'bar'
        }]
    };
    console.log(option.dataset.source)

    chart.setOption(option);
    return chart;
}

initChart这个方法传多一个data值
