Line Graph Creator

This Line Graph Maker creates a variety of line graphs and accepts negative values (e.g. -20). It is free to use and no account or log-in is required.

Line graphs are commonly used in geography fieldwork to compare data or illustrate trends over time. Line graphs can be used if the data are numerical and continuous (e.g. changes over distance) and are better than bar charts for comparing small changes or differences in data.

This line chart creator may also be used to construct cumulative frequency curves, based on running total data. The frequency for each class interval or x-axis plot is made cumulative by adding the running total of previous plot frequencies.

Enter your data in the calculator below. Select the type of line chart required and click the 'Calculate' button. Clicking the 'Open Line Chart' button will then open your line chart in a new window. A menu appears above the chart offering several options, including downloading an image. Hover over the chart to display the data.

The 'Customise' button opens options to edit the chart title and axes labels, as well as adjust the axes ranges.
