Arguments: chart-widget &key item-index object-index item-id object-id (value-type :value)
Returns an individual value that is in a chart-widget
. This could be a value that was
added by calling set-chart-value or a value that's returned by
the widget's chart-value-returner function if it has one.
The value will be nil
if the chart does not
contain a value for the specified item, object, and value-type, and
otherwise it will be a number.
chart-widget is the widget to be accessed.
The keyword arguments are:
nil
to not specify
an item index. Either this argument or item-id
must be true. item-index takes precedence if both
are true. The widget's
chart-item-id-equality-test is
used to find a matching item-index.
nil
to not
specify an object index. The default is zero if neither this argument
nor object-id is true.
object-index takes precedence if both are true.
The widget's
chart-object-id-equality-test
is used to find a matching object-index.
nil
to not specify an ID.
:value
: the "main" value of a chart item and object
pair.
:from-value
: an optional starting value for a bar in
a bar graph.
:high-value
: an optional value that's normally
greater than the main value.
:low-value
: an optional value that's normally less
than the main value.
:icon-size
: an optional size for a built-in icon
drawn on a line graph.
