The PPAR variable

Press J to recover your variables menu, if needed. In your variables menu

contents of this variable in the stack. Press the down-arrow key, , to launch

the stack editor, and use the up- and down-arrow keys to view the full contents

of PPAR. The screen will show the following values:

PPAR stands for Plot PARameters, and its contents include two ordered pairs of

real numbers,

(-8.,-1.10797263281) and (2.,7.38905609893),

which represent the coordinates of the lower left corner and the upper right

corner of the plot, respectively. Next, PPAR lists the name of the independent

variable, X, followed by a number that specifies the increment of the

independent variable in the generation of the plot. The value shown here is

the default value, zero (0.), which specifies increments in X corresponding to

1 pixel in the graphics display. The next element in PPAR is a list containing

first the coordinates of the point of intersection of the plot axes, i.e., (0.,0.),

followed by a list that specifies the tick mark annotation on the x- and y-axes,

respectively {# 10d # 10d}. Next, PPAR lists the type of plot that is to be

generated, i.e., FUNCTION, and, finally, the y-axis label, i.e., Y.

The variable PPAR, if non-existent, is generated every time you create a plot.

The contents of the function will change depending on the type of plot and on

the options that you select in the PLOT window (the window generated by the

simultaneous activation of the „ and ò(B) keys.
