The Label Item

To add a label, click the label Add label icon, place the element with the left mouse button on the Print Composer canvas and position and customize its appearance in the label Item Properties tab.

The Item Properties tab of a label item provides the following functionality for the label item (see Figure_composer_label):

Main properties

  • The main properties dialog is where the text (HTML or not) or the expression needed to fill the label is added to the Composer canvas.
  • Labels can be interpreted as HTML code: check checkbox Render as HTML. You can now insert a URL, a clickable image that links to a web page or something more complex.
  • You can also insert an expression. Click on [Insert an expression] to open a new dialog. Build an expression by clicking the functions available in the left side of the panel. Two special categories can be useful, particularly associated with the atlas functionality: geometry functions and records functions. At the bottom, a preview of the expression is shown.

Appearance

  • Define Font by clicking on the [Font...] button or a Font color selecting a color using the color selection tool.
  • You can specify different horizontal and vertical margins in mm. This is the margin from the edge of the composer item. The label can be positioned outside the bounds of the label e.g. to align label items with other items. In this case you have to use negative values for the margin.
  • Using the Alignment is another way to position your label. Note that when e.g. using the Horizontal alignment in radioButtonOnCenter Position the Horizontal margin feature is disabled.
