Using Graphs & Geometry 91
You resize the grid by rescaling the axes.
To turn the grid off:
f From the View menu, select the Hide Grid tool ( ).
When the tool is selected, the page updates to remove the grid.
In addition, you can attach a function, graph, or object to the grid while
the grid is displayed.
Attaching an object to the grid
1. Display the grid on the page if it is not already present.
2. Draw an object on the grid. Positioning the object so that points
coincide with grid marks attaches the object to the grid.
For example, if you draw a triangle, then one or more of the vertices
must coincide with grid marks.
Note: You do not have to attach an object or graph to the grid. When
you attach an object to the grid, its subsequent relocation is constrained
to other grid points. Analytic objects are affected by axes changes
regardless of whether or not they are attached to the grid.
To unattach an object from the grid, select and redefine it so that points
do not coincide with grid marks. If you hide the grid, objects attached to
it remain displayed on the page and remain attached to the grid even
though it is no longer visible.
The Zoom feature
For screens with many function graphs, it can be difficult to view
intersections and other areas of interest. To temporarily change your
view of the screen, use the Zoom feature.
