====== Dataset Legend : General Settings ======

This page describes all functions of the Orbit desktop [[112:orbit_desktop:datasets:legend:index|Legend Editor]] "General" tab :
  * Legend file description.
  * Sequence of model rendering if the dataset contains multiple models ([[112:technologies:basic_concepts:dataset_structure|]]).
  * Scale range limitations for each model individually.

=== Descriptions ===

Legend File and Location : Storage location of the dataset [[112:technologies:resources:other:olg|Orbit Legend File]] (*.olg). \\
Legend Description : Optional description, useful when having multiple legend files for one dataset. This description can be added to the [[112:orbit_desktop:datasetlist:dataset:legenddisplay|]] via the checkbox below.

=== Render Models in this sequence =====

It is possible to set the order of rending  models within one dataset. Overlying models will cover underlying models. It is advised to respect the model spatial type, from top to bottom : points, lines, areas and image models.

Select the model and use the appropriated Up and Down buttons at the bottom.

=== Scale Ranges for Models ===

Restrict the display of spatial (objects) and layout (labels, pie charts) component of each dataset model on [[112:orbit_desktop:map:index|Map 2D]] to a well defined scale range. Outside scale ranges the components won't be displayed. \\
To set a single scale range limit for the entire dataset and for more information about scale range limits, see [[112:orbit_desktop:datasets:general:index|]].

Remarks on dataset legend scale range limits :
  * Scale ranges on dedicated dataset components can be useful to simplify the map presentation to improvie the overal readability. 
  * Contrary to dataset scale range limitation, the dataset user name won't be displayed italic when dataset legend scale range limits are applied, see [[112:orbit_desktop:datasetlist:operations|]].
