How to highlight line and all point in echarts

I am using echarts with Vuejs. Behavior of chart is hover line. Line will be highlight and all point will be show like this. default when mouse hover

I try to use option emphasis of series of type line. But it make only highlight line. not work for item style. like this I want to default the all point not show. and all point will be show when emphasis active. But document of echarts not mention of this issue. Here is my config:

        itemStyle: {            color: '#fff',            borderColor: color,            borderWidth: 3,            opacity: 0,          },          lineStyle: {            width: 2,            color,          },          emphasis: {            focus: 'series',            lineStyle: {              width: 3,            },            itemStyle: {              shadowBlur: 9,              shadowColor: color,              opacity: 1,            },          },  

With any idea, please give me advice. Thanks so much
