To add a diagram, open the vector's Layer Properties
window and then click on the Diagrams
tab. The Diagrams
tab, as shown in the following screenshot, has five sections, as well as a Diagram type
selector.
Note
QGIS supports the addition of three diagram types as overlays on top of vector data. The three diagram types are pie chart, text diagram, and histogram. The underlying vector data can still be styled to provide a nice base map.
TheDiagram type
selector allows you choose which type of diagram to use: Pie chart
, Text diagram
, or Histogram
. When you choose a type of diagram, the other five sections change to contain the options that are appropriate for the diagram type.
The sections are Attributes

, Size
, Placement
, Options

. Attributes
is common to all diagram types and provides the mechanism for adding attributes to diagrams. Size
and Placement
contain parameters that are shared by all of the diagram types. Appearance
