# Graph paper in postscript format

## Some helpful comments

These postscript files are for printing out graph paper. You
should be aware that the department pays for each page, so please
don't print out whole pads of paper.

Please print out a copy of
*Experimental and analytic predictions*
(.ps or
.pdf)
for guidance on presenting data in computer science
classes.

As you know, plain graph paper is universally helpful for presenting
data. Semi-log paper is useful for presenting rapidly growing
functions. In particular, if you print an exponential function on
semi-log paper, you'll end up with a straight line. The slope of the
line determines the base of the exponent. If you turn semi-log paper
on it's side, you can use it to plot logarithmic functions; again, you
should get a straight line.

On log-log paper, polynomials end up looking like straight lines. The
slope of the line determines the degree of the polynomial.

If you've never seen log-paper before, the bottom row (marked ``1'')
is 1 unit. The next line marked ``1'' is 10 units. The next ``1''
after that is 100 units, then 1000. The very top line would be
100,000 on the 5-cycle semi-log paper.

## The graph paper

- Plain 30x40 graph paper (.ps or .pdf)
- Plain 39x52 graph paper (.ps or .pdf)
- Plain 30x40 graph paper (.ps or .pdf)
with every 5
^{th} line darkened
- Plain 39x52 graph paper (.ps or .pdf)
with every 5
^{th} line darkened
- 5-cycle semi-log paper (.ps or .pdf)
good for most semi-log graphing
- 10-cycle semi-log paper (.ps or .pdf)
can be good for projecting out as far 10
^{10}
- 2-cycle by 3-cycle log-log paper (.ps or .pdf)
- 5-cycle by 6-cycle log-log paper (.ps or .pdf)

## An example

The function 2^{n}
plotted on semi-log
paper (.ps or poor .pdf). Note how the point (0,1) -- *not* (0,0) -- is in the lower left.
The point (0,0) would appear infinitely far below the bottom of the page.
