## Graphs[ GCSE.com | Glossary ] | ||

[ Home | Wordprocessing | Spreadsheets | Desktop Publishers | Equations ] Graphs are very important in science, although it is often possible to create far too many of them with your computer. As a general rule, decide what you want the graph to show, before trying to create it. Don’t just create a graph of everything that you have. Spreadsheets can easily be used to create ## Unlabelled scatter graphAs it stands, this isuseless unless a full explanation comes with it. What it should have is:
- A
**title**, briefly stating what it shows. - Correctly labelled axes, including the
__units__. - A hand-drawn line through the points. In this case, a smooth curve. Sometimes a best fit line should be drawn.
**Never**join the points up with a zig-zag! Specialised software will allow you to fit a*curve*through the data points; spreadsheets normally won't.
The graph should be Generally, we tend to use line graphs (i.e. single points plotted on a graph, with a line through them) more than any other. In addition to the title, a graph and table should also have a table or figure number. When referring to either in your write up, it is better to talk about With a little effort, the graph can be labelled, boxed (if only using half a page) and titled (fig. 1).
