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.
