Controlling What Appears on a Graph Screen
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 fi t 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
E 97 to 9.999999999E 97
