The -s option allows you to suppress (i.e., to avoid drawing) selected features of your plots. The sub-options following -s specify which elements to suppress. The sub-options are as follows:
| e | don't begin a new page (erase screen) before plotting |
| a | suppress anything associated with axes |
| x | suppress anything associated with the x axis |
| y | suppress anything associated with the y axis |
| g | suppress the grid |
| m | suppress x axis and y axis tick marks |
| n | suppress x axis and y axis tick mark numbers |
| t | suppress titles for x axis, y axis, and graph |
| l | suppress user-supplied labels (-hl, -vl, -l, and -L options) |
| p | suppress all data plotting |
| f | suppress all ``figures'' (boxes, line segments, arrows, and legends) |
| C | enable all plot features (undo effects of previous -s sub-options) |
| X | subsequent -s sub-options apply only to the x axis |
| Y | subsequent -s sub-options apply only to the y axis |
| A | subsequent -s sub-options apply to both axes (default) |
Two or more sub-options can be grouped, as in:

By default, data points that fall outside of the axis limits are suppressed. If any data points are not plotted for this reason, plt produces a warning message indicating the number of points that were excluded from the plot. The -ex option overrides this behavior:
