Chapter 4 Graphing

4. To exit the View Window, press Q.

•Pressing w without inputting any value also exits the View Window.

• The following is the input range for View Window parameters.

–9.99E+97 to 9.999E+97

•You can input parameter values up to 7 digits long. Values greater than 10

less than 10

-1

, are automatically converted to a 4-digit mantissa (including nega-

tive sign) plus a 2-digit exponent.

• The only keys that enabled while the View Window is on the display are: a to

j, ., E, -, f, c, d, e, +, -, *, /, (, ), ! 7,

Q. You can use - or - to input negative values.

• The existing value remains unchanged if you input a value outside the allow-

able range or in the case of illegal input (negative sign only without a value).

•Inputting a View Window range so the min value is greater than the max value,

causes the axis to be inverted.

•You can input expressions (such as 2π) as View Window parameters.

•When the View Window setting does not allow display of the axes, the scale for

the

y-axis is indicated on either the left or right edge of the display, while that for

the x-axis is indicated on either the top or bottom edge.

•When View Window values are changed, the graph display is cleared and the

newly set axes only are displayed.

•View Window setting may cause irregular scale spacing.

•Setting maximum and minimum values that create too wide of a View Window

range can result in a graph made up of disconnected lines (because portions of

the graph run off the screen), or in graphs that are inaccurate.

• The point of deflection sometimes exceeds the capabilities of the display with

graphs that change drastically as they approach the point of deflection.

•Setting maximum and minimum values that create to narrow of a View Window

range can result in an error (Ma ERROR).
