Use the 3D-plot window Set > Plot Range > Length/center command or press Ctrl+N to examine and/or set the plot region parameters.  The dialog box displays the current length, center coordinate, and scale of the plot region in the x, y, and z directions, and invites you to enter new ones.  The lengths and center coordinates are also continuously displayed on the 3D-plot window status bar.


After you enter new plot region parameters, press OK to accept the new values.  The plot window will be redrawn and all expressions replotted.  Press Reset to restore the default plot region parameters (i.e. 10 for the lengths, 0 for the center coordinates, and 2 for the scales).  Press Cancel to cancel the command and make no changes to the plot region.


You can also change the lengths of the plot region using the zoom commands on the plot window’s command toolbar or by the function keys.  Zooming in magnifies details by displaying a smaller portion of the surface.  Zooming out shrinks details by displaying a larger portion of the surface.  You can zoom in the x direction, the y direction, or both directions at once.  When you zoom in or out, the length of the plot region is changed to the next closest number in the sequence: ... 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20 ... .


Use the following command toolbar icons or function keys to zoom the plot region in or out (i.e. to decrease or increase the plot range):

Click on the icon or press the F9 key to zoom both the x and y directions in.

Click on the icon or press the F10 key to zoom both the x and y directions out.
