On and hold off usage when Matlab drawing

The MATLAB Help document is as follows:

Hold on holds the current plot and all axis properties, including the current color and linestyle, so that subsequent grap Hing commands Add to the existing graph without resetting the color and LineStyle. Hold OFF returns to the default mode whereby PLOT commands erase the previous plots and reset all axis properties before D Rawing new plots.

corresponding translation
hold on: maintains the current drawing and all axis properties, including the current color and linetype, so that subsequent drawing commands are added to the existing drawing without resetting the color and linetype. Hold off: Returns to the default mode, whereby the plot command erases the previous drawing and resets all axis properties before drawing a new diagram
