Making a Basic Plot
To make a basic plot, choose P1 and P2 coordinates for the plot size you
desire and set the plotter to these values. The typical coordinates
shown in Table 5-1 on page 304 create a plot with approximately 1 in
margins on an 8-1/2 in by 11 in sheet of paper. (Many plotters have
default values for this size of paper.) You can enter coordinates in a
program directly, or query the plotter for the values. The latter method
is used in the example program below. To generate a plot, connect the
plotter via GPIB to the computer and execute Example 1.
