How to Draw a Line Graph
When a scientist carries out an experiment or makes observations, the results are often taken as measurements. These measurements are then presented as a table. For example, the results (left) show the growth of a baby badger. (A badger is a carnivorous mammal which is found throughout Europe and Asia.)
These results show clearly that the badger grows a lot during its first ten months. You can show these results more clearly if you draw a graph of them using graph paper.
To make a graph you must first draw two lines called axes (singular: axis). Use a sharp HB pencil and a ruler to do this. One axis is drawn horizontally across the page and the other vertically up the page.
Leave a margin next to each axis to write in.
The numbers are marked along the axis at regular intervals, for example 1, 2, 3, 4, 5, 6.
Next you plot the results on the graph :
Finally you draw a line between the points and give the graph a good title :
