Each axis now takes its own tick marks, and the value axes a prefix and
suffix for their numbers:
https://helpx.adobe.com/illustrator/desktop/automate-visualize-data/visualize-data/change-graph-value-axes.html
- Value axes (the left one, or a bar graph's bottom one, and the right
one): tick marks of no, short or full length, and a count per
division; labels stay at the divisions.
- Category axis: the same, at the labels or, with Draw Tick Marks
Between Labels, between them (halfway between labels when they sit
at the plot's edges).
- Add Labels: prefix and suffix per value axis ($, %).
- The Graph Type dialog offers the lengths and value axis sides as
choices, and counts it sends back as floats are read.
Own choices, as the page doesn't say: the lengths are none, short (the
4 pt ticks as before) and full (across the plot); category axes start
with no tick marks, as they had none before. Counts are capped at 20
per division and 10,000 category tick marks, affixes at one line of 64
characters. A full-length tick on the zero line or an axis line is left
out.
The legend moves past a bar graph's last value label when a suffix
runs it into the legend's gap. New fields are written only when set;
graphs with the default options draw the same art as before.
The value axis can now go on the left side (as before), the right side
or both sides of column, stacked column, line, area and scatter graphs:

With the axis on both sides, Separate Scales gives the series assigned
to the right axis a scale of their own there, with its own tick values
(rightTicks, rightAxisMin, rightAxisMax):
https://helpx.adobe.com/illustrator/desktop/automate-visualize-data/visualize-data/assign-different-scales-to-value-axes.html
- A series goes on an axis with Group Selection (or `seriesIndexes`)
and `valueAxis` left or right. Without separate scales both sides
show the one scale.
- Each axis stacks its own stacked columns and areas; stacked columns
of the two axes take a slot of the cluster each instead of covering
each other.
- An axis with no series of its own shows the other one's scale. The
right scale's zero gets a line of its own when it isn't the left's.
- The right axis' labels push the legend further right.
- With series on both axes picked, the Graph Type query returns no
value axis, so the dialog's OK leaves each series where it is.
- Graph Data drops right-axis assignments for series the new data no
longer has.
Own choices, as the pages don't say: bar graphs keep their value axis
along the bottom, and scatter graphs draw every series on one scale.
New fields (valueAxis, separateScales, rightSeries, rightTicks,
rightAxisMin, rightAxisMax) are written only when set, so other files
are unchanged and older versions draw the left axis as before. Graphs
with the axis on the left draw the same art as before.
Graph Type on series picked with Group Selection (or listed in the new
`seriesIndexes` param) now sets the type of those series only, so a
column graph can carry a line series:
https://helpx.adobe.com/illustrator/desktop/automate-visualize-data/visualize-data/combine-different-graph-types.html
- Column, stacked column, line and area mix on the vertical value axis;
bar and stacked bar on the horizontal one. Scatter, pie and radar take
no other type. The help page doesn't list which types mix, so this is
our own choice: types that share the value axis.
- Stacked columns take one slot of the column cluster (a graph of
stacked columns only is unchanged); stacked series stack with each
other, areas with each other, and the value axis covers both totals.
- Areas draw at the back, lines in front of columns. Category labels,
areas and lines sit at the category centres once a series that isn't
edge to edge is in the graph.
- With only series selected, the Graph Type query returns their type,
so the dialog's OK keeps it, and they stay selected after the change.
An explicit `id`, or anything else in the selection, is the whole
graph, as before.
- A series given the graph's own type follows the graph again. A type
the graph's type can't take is drawn as the graph's and kept.
Series types are stored in a new `seriesKinds` field, written only when
a series has its own type; versions that don't know it draw the whole
graph as the graph's type. Graphs of one type draw the same art as
before.
A graph's data can now hold blank cells: an empty CSV cell, a null in
`rows` (any cell that isn't a finite number), the rest of a short row,
or a row that has only a label.
- Columns, bars and stacked segments leave a blank cell out instead of
drawing a zero-height mark.
- Line and scatter graphs break their lines around it and draw no
marker there; the value axis ignores it.
- Area, pie and radar graphs draw it as 0, which is what it adds to
them.
The help pages don't describe blank cells, so this is our own choice:
a cell with no value has nothing to draw, which also matches how a
series with a missing year reads in a report.
In the file a blank cell keeps a 0 in `rows` and is listed in a new
`blanks` field ([category, series] pairs, written only when there are
any). A version that doesn't know blanks ignores the field and reads
the zeros, so files still open there, and files without blanks are
unchanged.
A number in straight quotes is a label, as the help page on graph
labels says (a year as a category name, for one). The CSV reader used
to strip the quotes first and read it as a value. Label columns are now
decided for the whole column: once any row starts with a label, every
row's first cell is its label, so a row with an empty label no longer
shifts its values one place left. The data window writes a header row,
labels that are empty, read as numbers or have spaces around them in
quotes, and blanks as empty cells, so they come back as they were.
graph.setData {} returns blanks in `rows` as null, so the rows it
returns can be edited and sent back. A label-only row keeps its place
with blank values; a row with neither a value nor a label is dropped,
and a first row that is a label followed by empty cells (`Year,,`) is
still read as a header with no series names.
The data grid is built in full for drawing and for the data window, so
it now stops at 10,000 categories of 256 series, which keeps a file
with one very long row from allocating without bound.
Behaviour (quoted labels): Add graph labels and data sets:

New line graphs put their points at the centres of their categories, the
option's default in the reference app; graphs saved before the option
existed were drawn edge to edge and keep it (a field default of its own).

Line graphs take the Edge-to-Edge Lines option (`edgeToEdge` on
graph.setType). On, the lines run across the whole plot, which is how
they always drew and stays the default, so existing graphs and files
look the same. Off, the points sit at the centres of their categories,
like the columns of a column graph, so a line graph lines up with a
column graph of the same size. The page describes only what the option
does when on; the off position is its opposite.
Radar graphs drew their ring and markers whatever Mark Data Points and
Connect Data Points said. They now follow both, like line and scatter
graphs.
Behaviour: Format columns, bars, and lines, Graph Type options for
line, scatter and radar graphs (Mark Data Points, Edge-to-Edge Lines,
Connect Data Points):

Group Selection's fill and stroke on a graph series are kept on the graph,
separately per series, and reapplied when its data, type or size changes,
and through save, open and undo.
