Column/bar graphs
Column graphs should be chosen when the independent variable (on the horizontal axis) occurs in discrete categories eg food types, species, colour. The vertical axis in a column graph represents numerical data.
-
The columns should be drawn so that they are not in contact with one another to indicate the lack of continuity.
-
The columns should be the same width and drawn with a ruler.
-
Avoid shading the columns, unless a multiple column graph is drawn, in which case a key is required.
