- function hold(opt_hold_state);
- %HOLD Hold the current graph.
- % HOLD ON holds the current plot and all axis properties so that
- % subsequent graphing commands add to the existing graph.
- % HOLD OFF returns to the default mode whereby PLOT commands erase
- % the previous plots and reset all axis properties before drawing
- % new plots.
- % HOLD, by itself, toggles the hold state.
- % HOLD does not affect axis autoranging properties.
- %
- % Algorithm note:
- % HOLD ON sets the NextPlot property of the current figure and
- % axes to "add".
- % HOLD OFF sets the NextPlot property of the current axes to
- % "replace".
