plot-values-min-index

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.
