A line graph (or line plot) is used to display related data that changes continuously over a given time period. The x and y values are plotted on the graph and the points are plotted and then joined with straight lines. When introducing line graphs, a good starting point is a line graph to show temperature change over a week in the local area – here, the days of the week would be marked off on the x axis, with temperatures on the y axis.
Students should be able to draw line graphs and also interpret their graphs, describing the change over time or comparing two data sets. A double line graph has two sets of related data plotted – for example, the changes in temperature over a week in summer and in winter. This makes it easier to compare and analyse the data sets. The gradient of a straight line segment joining two points on a line graph tells us about the rate of change in that time period – a steeper gradient represents a larger change.
Unlike pie graphs and pictographs, line graphs are not suitable for displaying discrete data, as joining the points implies that the data is continuous.
