About saving

When you are modelling data in PhixFlow, you will be making changes

• to a model, the components it includes and its layout
• to settings for the model, or for specific components. 

When you save the settings, also remember to save the model.

There are two ways to save settings. In the settings tab, use one of the toolbar icons:

• Insert excerpt
  _to_save _to_save nopanel true

• Insert excerpt
  _to_finish _to_finish nopanel true

  
  
  

Create and open a new model

1. In the repository browser, expand Full Repository, then Analysis Models.
   

   Expand
   title How?
   Insert excerpt _how_expand_repository _how_expand_repository nopanel true

   
   

2. To create a new model, right-click on Analysis Models and select 

   Insert excerpt
   _add_object _add_object nopanel true

    Analysis Model.

3. PhixFlow displays a settings tab for a new analysis model. In Basic Settings, set:
   Name: Introduction to Modelling

4. Click 

   Insert excerpt
   _save _save nopanel true

   .
5. In the settings tab toolbar, click 

   Insert excerpt
   _display_model _display_model nopanel true

   . PhixFlow opens an empty model.

Add components to your model

To drag a modelling component into your model:

1. Click and hold the 

   Insert excerpt
   _add_stream_calculate _add_stream_calculate nopanel true

    icon.
2. Drag the icon onto the modelling pane.
3. Then drop the icon. 

To move any component icon in a model, simply click, drag, then drop the icon in a new location.

When you have multiple components in your model, you can also use the layout tools to arrange them: 

Change component settings

When you drop a component into the model, on the right PhixFlow opens a settings tab.

1. In the stream settings → Basic Settings, set:
   Name: Practice Stream
2. Click 

   Insert excerpt
   _finish _finish nopanel true

    to save and close the settings tab.
3. PhixFlow updates the stream icon in your model to display the name Practice Stream.
4. Now save your model. Click

   Insert excerpt
   _save _save nopanel true

    in the modelling pane toolbar.

Undo a change to a model

Sometimes you may make a change to a model that you do not want to keep. To reverse a change

1. In your model, drag the stream to a different location.
2. Without saving, click 

   Insert excerpt
   _refresh _refresh nopanel true

   .
3. You will see the model return to its previously saved layout.
