So i was able to get it working with
`emphasis: { lineStyle: { color: s.color } }`
This is my entire code, I hope it helps you
`const getLineChartOptions = (data: TLineChartData) => ({
tooltip: xyTooltip,
grid: xyGrid,
xAxis: categoryAxis(data.labels),
yAxis: valueAxis,
series: data.series.map(s => ({
...s,
type: 'line',
smooth: true,
emphasis: { lineStyle: { color: s.color } },
})),
});`
