Θ Enter lower and upper limits for vertical view (V-View), and press @AUTO,
while the cursor is in one of the H-View fields, to generate the horizontal
view (H-View) range automatically.
Θ The calculator will use the horizontal view (H-View) range to generate data
values for the graph, unless you change the options Indep Low , (Indep) High ,
and (Indep) Step . These values determine, respectively, the minimum,
maximum, and increment values of the independent variable to be used in
the plot. If the option Default is listed in the fields
Indep Low , (Indep) High ,
and (Indep) Step , the calculator will use the minimum and maximum values
determined by H-View .
Θ A check on _Pixels means that the values of the independent variable
increments ( Step: ) are given in pixels rather than in plot coordinates.
