Type AreaChart

	Curve ChartCurve
	// Stack selects how the series combine at one X. Stacked series must not be
	// negative: a negative value stacks as zero (its tooltip still shows it).
	Stack ChartStack
	Fill  ChartFill
	// Dots marks every data point, as the dotted line chart does.
	Dots bool
	// StrokeWidth is the line width in logical pixels. Zero is 2.
	StrokeWidth float32

	Grid         ChartGrid
	Legend       ChartLegendPosition

	// Tooltip configures the hover tooltip; its Label is replaced by the X label
	// of the hovered point and a zero Layer is 4.
	Tooltip     ChartTooltipOptions
	HideTooltip bool
	// ValueFormat writes a tooltip value. Nil writes the shortest exact decimal.
	ValueFormat func(dst []byte, v float32) []byte

	// Label names the plot for assistive technology.
	Label string
	// Version identifies the data and its formatting. Bump it when either
	// changes: the chart caches axis labels and tooltip text per version.
