The Qt Graphs module provides a way to develop rapidly responding, complex, and dynamic 2D graphs for analytically demanding industries such as academic research and medicine. Qt Graphs provides 2D bars, lines, and scatter graphs. Combining user interaction and real-time 2D drawing graphs enables the creation of user interfaces that use space effectively.

The Qt Graphs module provides the following 2D graph types:
GraphsView is the base container for all 2D graph types, into which graphs are added as series.
The data is drawn as a series of vertical bars grouped by category, with one bar per category from each bar set added to the series.

A line graph is used to show information as a series of data points connected by straight lines. For each point, two values are specified that determine its position on the horizontal axis and the vertical axis.

The scatter data is displayed as a collection of points on the graph. For each point, two values are specified that determine its position on the horizontal axis and the vertical axis.
