To specify the coordinate range and drawing precision for drawing a 3D graph
Use the View Window to input values for the items below.
• x Minimum, x Maximum, x Grid ( x -axis minimum value
• y Minimum, y Maximum, y Grid ( y -axis minimum value
• z Minimum, z Maximum ( z -axis minimum value
To specify the range and drawing precision for each of the parameters (S and T) of a parametric type
graph
These settings are applied when drawing parametric graphs. Use the View Window to input values for the items
below.
• S Minimum, S Maximum, S Grid (parameter S minimum value
• T Minimum, T Maximum, T Grid (parameter T minimum value
To adjust the viewpoint of the graph window
Use the settings below to adjust the viewpoint of the graph display with respect to the x -axis and z -axis. Always
specify a value in degrees, regardless of the current
Angle θ : Specifies the angle of clockwise rotation of the x -axis (-180° < θ < 180°) viewed from the positive end
of the x -axis (0°).
Angle φ : Specifies the angle rotation of the z -axis towards the back (0° < φ < 360°) viewed from the positive
end of the z -axis forward (0°).
To initialize the View Window settings
On the View Window menu, select [Pre-set Windows] > [Initialize].
*1 Input minimum/maximum values in the range where the absolute value is smaller than 1 × 10
*2 Input a grid value in the range 2 ≤ grid ≤ 50.
*3 The grid value specifies the number of calculation points (number of divisions) for drawing a graph within
the specified drawing range (from the minimum value to the maximum value). However, in the case of a
sphere and certain other graph forms, the grid value is the number of divisions of the graph itself rather than
the number of divisions of the drawing range.
Note
• The greater the x Grid and y Grid values, the more detailed the graph. Also note, however, that larger
values require more calculation, which means that the graphing operation takes more time.
• Graphing may be impossible if the x Grid and y Grid values are too small.
Displaying the Cross Section of a 3D Graph
You can display the cross section of a 3D graph sliced with any vertical plane relative to the x -, y -, or z -axis.
This operation is available for lines, planes, spheres, cylinders, or cones drawn using a template.
To display the cross section of a 3D graph
On the Graph tab that already shows a 3D graph, perform the operations in the table below.
To do this:
Display a cross section of a 3D graph sliced with a plane
perpendicular to the x -axis.
Display a cross section of a 3D graph sliced with a plane
perpendicular to the y -axis.
Display a cross section of a 3D graph sliced with a plane
perpendicular to the z -axis.
Example: To display a cross section sliced on a plane perpendicular to the x -axis of the sphere graphed for
