u V-Window Setting Precautions
Inputting zero for T
θ
ptch causes an error.
Any illegal input (out of range value, negative sign without a value, etc.) causes an error.
• When T
θ
max is less than T
θ
min, T
θ
ptch becomes negative.
You can input expressions (such as 2 π ) as V-Window parameters.
When the V-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 V-Window settings clears the graph currently on the display and replaces it
with the new axes only.
Changing the Xmin or Xmax value causes the Xdot value to be adjusted automatically.
Changing the Xdot value causes the Xmax value to be adjusted automatically.
A polar coordinate (
r =) or parametric graph will appear coarse if the settings you make in
the V-Window cause the T
θ
ptch value to be too large, relative to the differential between
the T
θ
min and T
θ
max settings. If the settings you make cause the T
θ
ptch value to be
too small relative to the differential between the T
θ
min and T
θ
max settings, on the other
hand, the graph will take a very long time to draw.
The following is the input range for V-Window parameters.

k V-Window Memory
You can store up to six sets of V-Window settings in V-Window memory for recall when you
need them.
u To store V-Window settings
1. From the Main Menu, enter the Graph mode.
2. Press !3(V-WIN) to display the V-Window setting screen, and input the values you
want.
3. Press 4(V-MEM)1(STORE) to display the pop-up window.
4. Press a number key to specify the V-Window memory where you want to save the settings,
and then press w. Pressing bw stores the settings in V-Window Memory 1 (V-Win1).
