Current hold state


tf = ishold
tf = ishold(ax)


tf = ishold returns 1 if hold is on, and 0 if it is off. When hold is on, the current plot and most axis properties are held so that subsequent graphing commands add to the existing graph.

tf = ishold(ax) returns the hold state of the axes specified by ax instead of the current axes.

A state of hold on implies that both figure and axes NextPlot properties are set to 'add'.
