There are many options that can be applied to the plot command, and other plots accept most of those options. They include grid display options (gridlines, axes, captions, and more), plot generation options (adaptive point sampling and discontinuity detection), and plot display options (colors, line and fill styles, transparency, etc). See plot options for a complete list. Each plot page indicates which of the options it accepts.
Most of the options that can be applied to a plot command can also be applied interactively to an existing plot, by using the plot context menus.
The plottools package provides commands to generate basic graphical objects and alter existing plot structures. Objects include geometric shapes, arrows, and points, and can be displayed either in existing plots or on separate axes. Transformations involve rotation, translation, and scaling of any type of plot. Also available is textplot, for adding text or 2-D math to an existing plot (or textplot3d for 3-D plots). You can also add text, 2-D math, various shapes, or free form drawing to a 2-D plot using a set of drawing tools.
Typesetting for 3-D plots provides the ability to use typeset mathematics and text in titles, captions, axis labels and text objects, as well as the ability to edit them in place. For more information, see the plot/typesetting help page.
The plot and plot3d commands have been updated to recognize units in the function and range arguments, for both the expression-form and operator-form of the calling sequences. More information about this feature is available on the plot/units help page.
You can set most plot options for an entire Maple session, using the setoptions command. The options apply only to the worksheet in which they are set, until either it is closed, or restart is called.
