Line graphs are usually used to show timeseries data (or other continuous variable e.g. distance), how one or morevariables vary over a continuous period of time.
In a line graph the x-axis (independent variable) represents the continuous variable (for example year or distance fromthe initial measurement) whilst the y-axis (dependent variable) has a scale andindicates the measurement.
Several data series can be plotted on thesame line chart and this is particularly useful for analysing and comparing the trends in different datasets.
