Arguments: chart-axis
Returns the value of the draw-major-labels property of
a chart-axis
. The value
may be set at creation time by passing
the :draw-major-labels
initarg, or any
time later by calling (setf draw-major-labels).
A value indicating whether (and how) label strings are drawn for the
major tic positions of a chart-axis
in a chart-widget
. Here are the possible values:
nil
- No labels are drawn for major tic
positions.
t
- Labels are drawn for major tic positions,
and are drawn directly outward from each tic position. This is the
default value.
:after
- Each major tic label is drawn midway
between its major tic position and the next major tic position. This
can be useful if the label actually refers to the span between the two
tics. For example, if there is a major tic for each year and a minor
tic for each month, then printing the year in
the :after
position for the major tic for the
beginning of the year will print the year in the middle of the minor
tics for the months of that year.
:after-nestled
- This is
like :after
, except that it will print the string
closer to the axis if the minor-tic-length is less than the
major-tic-length. It assumes
that the label will fit between the major tic marks and therefore need
only avoid overlapping the minor tic marks.
:before
- This is like :after
,
except drawing the label between its tic position and the previous
major tic position.
:before-nestled
- This like
like :before
in the way
that :after-nestled
is
like :after
.
