 Field
 =====
 
 A field object assigns some values to geometrical entities. These values can be later transferred to mesh entities generated on the geometrical entities during export to MED file in Mesh module. Geometrical fields can be stored in/restored from XAO format files. Note that only integer and double values can be exported into the MED file.
 
-The field can hold several named values (components) per a geometrical entity.
+The field can hold several named values (components) per geometrical entity.
 
 The field can include several sets of data called steps, each dedicated to a certain time moment.

+
+When a field is created then its result in data tree looks like following.

+.. figure:: images/field_steps_tree.png
+  :align: center
+
+  Result of created field with two steps.
+  
+It consists of a Field result object and steps as sub-objects. Only one object can be displayed at one moment: field or one of its step. Field result presentation repersents entities used for the Field definition.
+Step presentation shows field entities and values defined on them. For example a step defined on faces with double values looks like following.

+Color bar for displayed step is shown only if the setep is selected in **Object Browser**. Desirable parameters of the Color bar (position, number of intervals, text color) can be defined in **Preferences** dialog box.
