Question

我想用echarts来缩放时间轴（X轴）和Y轴。但我不知道怎么做，添加什么属性可以缩放X轴和Y轴？

我的意思是，当我的鼠标左键选择X轴的一部分时，我应该缩放所选部分。

您可以使用我的代码进行测试。现在我的代码：

    },
    yAxis: {
        type: 'value'
    },
    series: [

            name:'peter',
            type:'line',
            data:[1889,2930,2059,1948,1814,2071,2183,3234,3426,2188]

    ]
};
;
if (option && typeof option === "object") {
    myChart.setOption(option, true);
}
       </script>

您没有设置任何datazoom选项。

请参见https://echarts.apache.org/en/api.html#action.dataZoom
