在Echarts折线图中，要将小圆点设置为实心，可以使用option中的series属性进行配置。具体的配置如下所示：
```
series: [
{
name: 'Fake Data',
type: 'line',
smooth: true,
symbol: 'circle',
symbolSize: 5,
itemStyle: {
color: '#F2597F'
},
areaStyle: {
color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
{
offset: 0,
color: 'rgba(213,72,120,0.8)'
},
{
offset: 1,
color: 'rgba(213,72,120,0.3)'
}
])
},
data: data2
}
]
```
在上述代码中，将symbol属性的值设置为'circle'，即可将小圆点改为实心。同时，可以通过itemStyle属性中的color属性来设定小圆点和线的颜色。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
