Optional ReadonlycolorThe series colour. Absent takes the next colour from the built-in cycle.
ReadonlydataOne value per category, in the same order as CartesianChartData.labels.
A series shorter than the labels leaves the trailing categories empty rather than shifting; the two are matched by position, not zipped.
Optional ReadonlylabelThe series name, shown in the legend. Absent leaves it out of the legend.
One series of a cartesian chart.
