What is a line graph?
In a line graph (also called line chart or line plot) the data points of a series are plotted in sequential order and connected by a continuous line which reveals trends over the x-axis. You can use this vizzard also to represent ordinal data since its x-axis can be used as a category axis (ordinal scale).

What is the difference between a line graph and an area chart?
In an area chart, the areas between the horizontal axis and the series’ lines are filled with colors.
Both charts can be used to visualize one single series or to compare multiple series over a category or value scale. This graph maker enables you to choose between them or even combine lines and areas.
Because areas often overlap with each other, they can be more difficult to understand than lines. To minimize this risk and facilitate comprehension, the areas in this vizzard are light transparent.

Line Graph: What's new?
NEW Most of our data visualisations now support SI prefixes, advanced number format options for axes and shown data labels.
We fixed a bug that did not display your first data points when you switched between a continuous and a discrete horizontal axis.
Axis settings are getting more flexible: we have added the option to hide axis labels.
Improvement to the number formatting and the code base to avoid update loops.
We have improved the position of the first and last data point. They are displayed above the line. The option to show them before or after the end of the line is still available.
You can now hide vertical and horizontal axis lines.
