How echarts modifies specific column colors through click events of other dom

take the official tutorial as an example, assume that there are six buttons outside the canvas, corresponding to each item in the xAxis.data.
Click a button to make the opposite column green.
how can I implement it?
do I need to myChart.setOption (option) again every time I change color?

  var myChart = echarts.init(document.getElementById("main"));
        var option = {
            title: {
                text: "ECharts "
            },
            tooltip: {},
            legend: {
                data:[""]
            },
            xAxis: {
                data: ["","","","","",""]
            },
            yAxis: {},
            series: [{
                name: "",
                type: "bar",
                data: [5, 20, 36, 10, 10, 20]
            }]
        };
        myChart.setOption(option);

Yes, it is called every time, and there is no separately set method.
