When to use a Line Chart

If you have continuous data that you would like to represent through a chart then a line chart is a good option. This graph is especially effective when trying to identify a trend or pattern in your data, for example seasonal effects and large changes over time. A good example of a line chart can be seen below.

This type of chart is created by connecting a series of data points together with a solid line. The types of data normally represented in a line chart are annual employment rates and monthly rainfall as examples, as it will be clear to see the trend in the data over a continuous period of time.

Usually these graphs show time series data but they can display other continuous variables like distance, for example how the level of a chemical varies with depth of soil.

In general the continuous variable would be represented with the x-axis and the y-axis represents the measurement. The line chart is commonly used in many different fields, especially the experimental sciences as it is a good way to visualise the data collected from experiments.
