- graph.setData {transpose: true} swaps rows and columns (after any new
data in the same call); a graph with more categories than a graph can
have series (256) is refused rather than cut. {switchXY: true} swaps
each scatter series' y and x columns, labels included.
- A `|` in a category or series label starts a new line: legend rows
grow with their lines, labels beside an axis or in a wedge centre
theirs. A label of only `|` is blank.
- Pie graphs: pieLegend none|standard|wedges (Legends in Wedges puts the
series labels inside their wedges, in white on dark wedges, drawn over
the pies), piePosition ratio|even|stacked and pieSort all|first|none,
as dropdowns in the Graph Type dialog, which lists them for pie graphs
only.
Own choices, as the page doesn't say: Position and Sort keep today's
drawing by default (Even, None); Ratio sizes pies by area, the biggest
keeping the full size; Stacked pies share a centre, each drawn as the
ring outside the next smaller one so none covers another, with their
names over them.
New fields are written only when set. Graphs with default options draw
the same art as before.
