| 5406 | 21 ## Tell Octave to `hold' the current data on the plot when executing |
| 22 ## subsequent plotting commands. This allows you to execute a series of | |
| 23 ## plot commands and have all the lines end up on the same figure. The | |
| 24 ## default is for each new plot command to clear the plot device first. | |
| 25 ## For example, the command | |
| 26 ## | |
| 27 ## @example | |
| 28 ## hold on | |
| 29 ## @end example | |
| 30 ## | |
| 31 ## @noindent | |
| 32 ## turns the hold state on. An argument of @code{"off"} turns the hold | |
| 33 ## state off, and @code{hold} with no arguments toggles the current hold | |
| 34 ## state. | |
| 35 ## @end deftypefn | |
