Graphs

Some important things to remember when drawing graphs.


1. Give your graph a title
2. Chose a sensible scale for both axes
3. Try and draw a graph that will fill the graph paper
4. Label the axes
5. Put units on both axes
6. Plot the points correctly
7. Mark the points clearly with a cross or with a heavy dot
8. Draw a smooth best fit line through the points. This is often called a trend line. It shows the general trend but you do not have to join up all the points – in fact you should not do this unless they actually fit the trend line.
9. Recognise any anomalous points (ones that are way off the general trend).
10. Draw the line clearly and finely
