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.
–9.999999999

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).
