Arguments: chart-view
Returns the value of the high-low-value-style property of
a chart-view
. The value
may be set at creation time by passing
the high-low-value-style
initarg, or any
time later by calling (setf high-low-value-style).
A value indicating the particular style in which
any :high-value
and :low-value
values in a chart-widget
are currently drawn. Here are the possible values:
:tee
- Each value is drawn as a thin line from the
main value to the high or low value, with a short perpendicular line
drawn at the high or low value to form a tee. This style is commonly
used to show an error range around a main value. This is the default
value.
:bar
- Each value is drawn as a filled rectangular
bar from the main value to the high or low value. This may be useful
when a more prominent annotation is desired than the more
common :tee
style.
:diamond
- Each value is drawn as a triangle with a
base at the main data value and proceeding to a single point at the
high or low value. When there is both a high and a low value, the
overall shape is that of a diamond. This style tends to look
heavy-handed on a line graph, but may be more useful on a bar chart.
