Arguments: chart-axis
Returns the value of the overlap-major-and-minor-labels property of
a chart-axis
. The value may
be set at creation time by passing
the overlap-major-and-minor-labels
initarg, or any
time later by calling (setf
overlap-major-and-minor-labels).
A boolean value indicating whether the area that is allocated for the
major tic labels of a chart-axis
in a chart-widget
overlaps the area that is allocated
for minor tic labels. The default value is t
.
When this property is true, both major and minor tic labels are printed just at the ends of the tic marks (with a small gap provided by the margin-inside-major-labels and margin-inside-minor-labels properties). If the label strings are sufficiently long, a major label and a minor label could run into each other. (A chart-widget by default will space things out so that successive major labels do not overlap each other, and so that successive minor labels do not overlap each other, but it does not guarrantee that a major label will not overlap a minor label when this property is true.)
When this property is nil
, then major labels
are printed in an area that is completely outside the area in which
minor labels are printed. This uses up more space, but guarrantees no
overlap between major and minor labels. This option also allows minor
tic labels to be printed at major tic positions, in addition to the
major tic labels; this can be useful, for example, to print a month on
every minor tic of an item-axis and a year on every major tic.
