Using the Graph Window
u View Window parameter precautions
•An error occurs if you input 0 for tθstep.
•An error also occurs if you input a value that is out of range for a parameter, if you input a minus sign only, or if you perform any other illegal input.
•An error occurs if ymin is greater than or equal to the ymax. The same is also of the xmin and xmax. If the value you specify for tθmin is greater than the value you specify for tθmax, the tθstep setting is automatically changed to a negative value.
•When the View Window setting produces an axis that does not fit on the display, the scale of the axis is indicated on the edge of the display closest to the origin.
•Changing the xmin (ymin) or xmax (ymax) value automatically changes the xdot (ydot) value, while changing the xdot (ydot) value automatically changes the xmax (ymax) value.
u To initialize View Window parameters
(1)On the application menu, tap T.
(2)Tap 6. This displays the View Window dialog box.
(3)Tap [Memory] and then [Initial]. This initializes View Window parameters to the values noted below.
xmin = | xmax = 7.7 | xscale = 1 | xdot = 0.1 |
ymin = | ymax = 3.8 | yscale = 1 | ydot = 0.1 |
tθ min = 0 | tθ max = 6.28318530717 | tθ step = 0.05235987755 | |
u To initialize the View Window for an angle unit
(1)On the application menu, tap T.
(2)Tap 6. This displays the View Window dialog box.
(3)Tap [Memory] and then [Trigonometric]. This initializes View Window parameters in accordance with the angle unit, as shown below.
(Setup: Radian)
xmin = | xmax = 9.42477796076 | |
xscale = 1.57079632679 | xdot = 0.12239971377 | |
ymin = |
| ymax = 1.6 |
yscale = 0.5 |
| ydot = 0.04210526315 |
tθ min = 0 |
| tθmax = 6.28318530717 |
tθ step = 0.05235987755 |
| |
(Setup: Degree) |

xmin = | xmax = 540 | xscale = 90 xdot = 7.01298701298 |
ymin = | ymax = 1.6 | yscale = 0.5 ydot = 0.04210526315 |
tθ min = 0 | tθ max = 360 | tθ step = 3 |
