Arguments: chart-widget
Returns the value of the scrolled-to-end-maintained property of
a chart-widget
. The value
may be set at creation time by passing
the :scrolled-to-end-maintained
initarg, or any
time later by calling (setf
scrolled-to-end-maintained).
scrolled-to-end-maintained is
a boolean value indicating whether modifying a chart-widget
that is scrolled to the
end will keep it scrolled to the end. The default value
is t
.
This property has an effect only when it is true and the widget
happens to be scrolled to the end of its data. In that situation, if
chart items are added or removed at the end of the data then the
widget is scrolled automatically so that it is still scrolled to the
very end of its data. This is also done if the chart-widget is resized
(which typically would happen if its right-attachment or bottom-attachment
is :right
or :bottom
and the
user resizes the parent window).
