Use a pencil and ruler to draw a giant "L" on the graph paper. Put a tick mark at every place the graph intersects a line on the graph paper.
Look at your sets of numbers to determine whether temperature is the dependent or independent variable. Temperature is the dependent variable if it varies according to something constant, it is the independent variable if it is constant while something else varies according to it. For example, if you are charting average monthly temperature, temperature is dependent on month, making it the dependent variable. Temperature does not effect what month it is, the month effects the temperature. Alternately, if you are charting hours of air conditioning use by temperature, since air conditioning use does not cause it to be a certain temperature outside, temperature is the independent variable and air conditioning use the dependent. The dependent variable will always be charted on the horizontal, or x-axis and the independent on the vertical, or y-axis.
Label the appropriate line of your graph according to the range of temperatures going out from the origin (the place where the lines meet). If the range is big, like from -2 to 94 degrees, mark each box counting by fives or tens from -10 at the origin to 100 at the end of the graph. If the range is smaller, count by ones. Next to the labels, label these numbers as "Temperature in" then specify whether the temperatures are in Celsius or Fahrenheit.
Label the other line of your graph in a similar fashion according to what the other data set is. If you are graphing temperature by month, write an abbreviation for the name of each month next to a tick mark on the horizontal line, if hours of heater use, write hour numbers going up the vertical axis. Beside these labels, label the axis as "Time," "Hours of Air Conditioning Use" or whatever it is.
Draw a point at each place where the data sets correspond. If the average temperature for January was 20 degrees Fahrenheit, find March on the x-axis, then go up to the approximate location of 20 degrees on the y-axis, and mark a dot where they intersect. If people average four hours of air conditioning use on 75 degree days, find 75 degrees on the x-axis then go up to four hours on the y-axis and mark the point where they meet.
Connect the dots once all points are graphed to notice patterns and chart how the data changes.
