The axis is laid out, so its series have a scale, but nothing of it is drawn.
OptionalgridlinesThe major gridlines, in px: a line across the plot at each tick of a value axis, and between
categories (or on them, midCat) of a category axis. Absent when the axis shows none.
The axis's id in the chart (axId).
null when the axis shows no labels.
Between the axis line and the near edge of its labels, in px.
OptionallabelsWhere the labels and tick marks are, in px as lineAt, where they do not go with the line: at
the plot's low or high edge (tickLblPos low or high, a 2016 chart's categories) while the line
crosses the other axis inside the plot. Absent where they go with the line.
OptionallabelThe labels are stacked letter over letter (vert="wordArtVert"): each label's letters are
joined by \n, labelLineHeight apart. Along the bottom or top a label too tall for half
the plot's outer height breaks into columns, joined by \t, side by side.
Where the axis line is, in px: the y of a horizontal axis, the x of a vertical one. On the
plot area's edge named by position, unless the axis crosses the other inside the plot (a
scatter's x axis at y = 0 when the y values straddle zero). Labels and tick marks go with it.
The axis runs from its maximum to its minimum (orientation maxMin): a vertical axis down,
a horizontal one right to left. A reversed category axis puts the first category at the top
or the right, and mirrors each cluster.
In px.
OptionalunitThe display unit label (dispUnitsLbl) of an axis whose values are shown in a unit, beside its title.
The id of the axis this one crosses.
