• You can use the set up screen settings to alter the appearance of the graph
screen as shown below.
• Grid: On
This setting causes dots to appear at the grid intersects on the display.
• Axes: Off
This setting clears the axis lines from the display.
• Label: On
This setting displays labels for the x- and y-axes.
• A polar coordinate (r =) or parametric graph will appear coarse if the settings
you make in the View Window cause the T,
θ
pitch value to be too large,
relative to the differential between the T,
θ
min and T,
θ
max settings. If the
settings you make cause the T,
θ
pitch value to be too small relative to the
differential between the T,
θ
min and T,
θ
max settings, on the other hand, the
graph will take a very long time to draw.
• Attempting to draw a graph for an expression in which X is input for an X =
constant expression results in an error.
