The column names, in order.
How many data points the series holds.
The category name at index.
Measured: the category axis' label on a category axis, and the empty string on a value axis -- so an empty name means "this axis carries numbers", not "this point is unnamed".
The value of one dimension at index.
On a category axis this is the category's index, not its name; the name comes from getName.
OptionalmapThe column one coordinate of the series reads -- 'x' to 'x' for data
written inline, and the column encode names for data fed from a
dataset, which carries every column of the dataset rather than only
the ones the series is drawn from. undefined for a coordinate the
series has none of. Optional because a hand-written list may lack it;
dimension.ts falls back to the column's position.
OptionalmapEvery column one coordinate of the series reads, in the order encode
lists them -- a box plot maps five onto its value axis.
OptionalgetWhere one datum was drawn, in the chart's CSS pixels. Its shape depends on
the series type, and a datum with no value comes back with a null
coordinate; canvas.ts records what was measured for each.
OptionalgetWhat ECharts computed about the list -- on a stacked series,
'stackResultDimension' and 'stackedOverDimension' name the columns
holding the top and the bottom of the band it draws, and
'stackedOnSeries' the series it rests on. Measured on echarts 6.1.0.
OptionalgetA layout of the whole series -- a line's 'points', flat [x0, y0, …].
OptionalgetOne resolved visual of one datum -- its 'style', its 'symbolSize'.
OptionalgetOne resolved visual of the whole series.
OptionaltreeThe hierarchy, on a treemap, sunburst or tree series.
OptionalgraphThe graph, on a sankey or graph series.
A series' data list.
Addressed by index rather than iterated, which is what lets a reading walk it in the order the chart drew it.
