# Producing quantitative diagrams

Until now, our diagrams presented objects in order or in relation to each other. Now, we will visualize and compare actual values utilizing diagrams.

## Line charts

Numerical data is often a series of values measured over time. These values can be displayed as data points on a plane, with the x axis for the time and the y axis for the values. Connecting lines show the trend over time. This is called a line chart. Such a chart can contain multiple line series to display different datasets to see them in relation. The x axis doesn’t need to represent time; it could be any other base value, such as age, weight, or other data to correlate with values.

In Figure 12.5, we saw how a line chart could be plotted, and Chapter 13, Plotting in 2D and 3D, showed tools to plot in a coordinate system. pgfplots provides a perfect setting to display values in a plane by lines or bars with annotations.
