====== Distance line tab ======

The **Distance axis** tab allows you to configure the information
displayed along the geographical axis of the Time-Location schedule.

This axis represents the **position of activities along the project**
(for example: kilometres, metres, or geographic reference points).

It is possible to add different **distance lines**
to enrich the readability of the schedule.

===== Interface organisation =====

The interface is composed of two main sections:

  * management of the **distance lines**
  * editing the **parameters of a line**

-----

===== Distance line management =====

The upper section allows you to manage the lines displayed
along the distance axis.

Two areas are available:

  * **Distance line**  
  corresponds to the primary axis visible in the view

  * **Opposite distance line**  
  allows additional information to be displayed on the opposite axis of the schedule

The **+** and **–** buttons respectively allow you to:

  * add a new line
  * remove an existing line

The arrows allow you to modify the display order
of the different lines.

-----

===== Distance line settings =====

The lower section of the interface allows you to modify
the parameters of the selected line.

You can define:

  * the **displayed value**
  * the **display interval**
  * the **font and text size**
  * the **line height**
  * the **text position**
  * the **background colour**

===== Available line types =====

Three types of lines can be used to enrich
the distance axis:

  * **Text**  
  to display chainage markers (km, metres, etc.)

  * **Sector**  
  to display project zones or geographical elements

  * **Image**  
  to display graphical elements along the alignment

The following sections explain in detail how to use
each of these line types.
