Area
An area series is a line with the region below it filled by a vertical gradient. It reads like a line chart but emphasizes the magnitude of a single value over time, which suits equity curves and price overviews.

Setup
Add an AreaSeries and feed it { time, value } points; topColor/bottomColor define the gradient:
const series = chart.addSeries(SSChart.AreaSeries, {
topColor: 'rgba(74,158,255,0.3)',
bottomColor: 'rgba(74,158,255,0.02)',
lineColor: '#4a9eff',
lineWidth: 2,
});
series.setData(candles.map(c => ({ time: c.time, value: c.close })));
chart.timeScale().fitContent();
