Arguments: chart-axis
Returns the value of the minor-tics-per-major-tic property of
a chart-axis
. The value
may be set at creation time by passing
the minor-tics-per-major-tic
initarg, or any
time later by calling (setf minor-tics-per-major-tic).
The number of minor tic positions per major tic position on a
chart-axis
in a
chart-widget
. The value
should be a positive integer, or else nil to use a default value. The
default value is nil
for
a value-axis
and 1 for an
item-axis
.
For a value-axis
, a value
of nil
causes the number of tics to be
computed automatically such that the increment from one minor tic
position to the next is a relatively "round" number. This is done
after the major-tic-increment
has been determined. For an item-axis
, a value
of nil
simply defaults to 1.
This value is actually the number of minor tic increments from one major tic position to the next. That is, if the value is 5 then 4 minor tic marks will be drawn between the surrounding major tic marks to measure 5 increments from one major tic mark to the next.
A value of 1 means that there are no minor tic positions between major tic positions, resulting in a chart that has only major tic marks, major tic labels, and/or major grid lines.
