echart 折线图去掉折线上面的小圆点

1、echart 折线图去掉折线上面的小圆点: 配置symbol: "none"

series:[{ symbol: "none", name: "seriesName", type: "line", data: [1,2] }]

2、折线图 x轴从0开始，xAxis 配置boundaryGap: false,

option = {
    title: {
        text: 'demo',
        subtext: '示例'
    },
    tooltip: {
        trigger: 'axis',
        axisPointer: {
            type: 'cross',
            label: {
                backgroundColor: '#283b56'
            }
        }
    },
    legend: {
        data:['test']
    },
    toolbox: {
        show: true,
        feature: {
            dataView: {readOnly: false},
            restore: {},
            saveAsImage: {}
        }
    },
    xAxis: [
        {
            type: 'category',
            name:'xAxisName',
            boundaryGap: false,
            data: [1,2,3,4,5,6,7,8,9,10]
        }
    ],
    yAxis: [
        {
            type: 'value',
            scale: true,
            name: '价格',
            max: 25,
            min: 0,
        },
        {
            type: 'value',
            scale: true,
            name: '数量量',
            max: 100,
            min: 0
        }
    ],
    series: [
        {
            name:'test',
            type:'line',
            data: [0,12,13,14,15,16,17,18,19,20]
        }
    ]
};
