Type ChartAreaStyle

type ChartAreaStyle struct {
	// Color overrides the series fill color. A zero color uses the series color.
	Color ui.Color
	// Opacity multiplies the fill alpha, clamped to [0,1]. Non-finite is zero.
	Opacity float32
	// Gradient overrides the endpoint colors of ChartFillGradient. Nil fades
	// Color (or the series color) using the chart's default alpha stops.
	Gradient *ChartAreaGradient
}

ChartAreaStyle controls a series' fill independently of its line. The pointer on ChartSeries is optional; an explicit zero Opacity is transparent, so use ChartAreaDefaultOpacity when only the color should change.
