Arguments: plot-widget
Returns the value of the plot-values-min-index property of a
plot-widget
. The value may
be set at creation time by passing
a plot-values-min-index initarg
to make-instance, or any time
later by calling (setf plot-values-min-index).
plot-values-min-index is the
index of the first plot value of a plot-widget that should be
displayed at the current time. The value should be a non-negative
integer, or else nil
to default to zero. The
default value is nil
.
If set-plot-value has been
used to add items to the plot, then any item whose index is less than
this property value (if it is a number) will not appear in the
plot. When the property value is nil
or zero,
then no items are excluded. This property can be used to display only
a subset of collected values that are of interest at the moment.
If instead a plot-value-returner function is used for looking up plot data, then this property could be used if your function handles a range of value indices that does not begin at zero.
