# Graph paper in postscript format

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.

You can find more professional paper at printefreegraphpaper.com

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 5th line darkened
Plain 39x52 graph paper (.ps or .pdf) with every 5th 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 1010
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 2n 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.
