2. Controlling What Appears on a Graph ScreenkV-Window (View Window) Settings

Use the View Window to specify the range of the x- and y-axes, and to set the spacing between the increments on each axis. You should always set the V-Window parameters you want to use before graphing.

uTo configure V-Window settings

1. From the Main Menu, enter the Graph mode.

2. Press !3(V-WIN) to display the V-Window setting screen.

Rectangular coordinate parameter

Xmin/Xmax … Minimum/maximum x-axis value

Xscale … Spacing of x-axis increments

Xdot … Value that corresponds to one x-axis dot

Ymin/Ymax … Minimum/maximum y-axis value

Yscale … Spacing of y-axis increments
