u V-Window Setting Precautions • Inputting zero for Tθ ptch causes an error. • Any illegal input (out of range value, negative sign without a value, etc.) causes an error. • When Tθ max is less than Tθ min, Tθ ptch becomes negative. • You can input expressions (such as 2π) 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 Tθ ptch value to be too large, relative to the differential between the Tθ min and Tθ max settings. If the settings you make cause the Tθ ptch value to be too small relative to the differential between the Tθ min and Tθ 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. -9.999999999E 97 to 9.999999999E 97 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.
