Chapter 4
� 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 106 or less than 10-1, are automatically converted to a 4-digit mantissa (including negative 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 allowable 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 2�) 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).
