A look at the application interface
====================================

The user interface of the ERTdesign *multisource* module consists of four components.

	Application interface.

1. One **Menu Bar** on the left of the screen with command-icons to show/hide the 
   *Side Panels* for accessing the application functionalities.

2. Four **Side panels** on the left of the screen, which are accessed by each one of the *Menu Bar* commands.

3. Three **Project tabs** with project details and analysis tools.

4. One **Graphical toolbar** at the bottom of tabs for managing the properties of plots.


Menu bar
---------
Shows/hides the *Side Panels* with functions for opening/saving project files, survey design, 
user preferences settings and access to documentation.

Side panels
------------
* The :doc:`Load and save <loadsave>` panel allows to open and save project files.

* The :doc:`Survey design <design>` panel contains the configuration commands 
  for the survey project: properties of the area to be investigated, receivers 
  and transmitters settings.

* The :doc:`Preferences <preferences>` panel allows for setting the application defaults.
  
* The :doc:`Info and documentation <info>` panel gives access to the documentation.
  

Project tabs
-------------
* The :doc:`Survey design summary <design_summary>` tab contains the details of the generated set of sensors.

* The :doc:`DOI/Vmn charts <design_doi-vmn>` allows to analyze sensitivity, depth of 
  investigation and expected Vmn signal for TX/RX combinations.

* The :doc:`TX/RX schedules <design_schedule>` contains sheets with coordinates of the generated 
  electrodes, with details on n-poles and with measurements pseudo-plots.


Graphic toolbar
----------------

The graphic toolbar allows to perform the most common operations on properties
of the graphs present in each project tab.

Looking at the bar controls from left to right we find:

* **Home, Back, Forward**. These commands are similar to *home, forward and back* of a web browser. 
  The *Forward* and *Back* commands are used to navigate back and forth between previously 
  defined views. The *Home* command takes back to the default data view.

* **Pan/Zoom**. This command has two modes: **pan and zoom**. Press the left mouse button 
  and hold it to pan the figure, dragging it to a new position. By pressing the "x" or "y" 
  keys while panning, the motion will be constrained respectively on the x or y axis. 
  Pressing the *right mouse button* zooms in. The x axis will be zoomed in proportionately 
  to the rightward movement and zoomed out proportionately to the leftward movement. The same 
  is true for the y axis and up/down motions.

* **Zoom on rectangular area**. Define a rectangular region by dragging the mouse while holding 
  the button to a new location. When using the left mouse button, the axes view limits will be 
  zoomed to the defined region. When using the right mouse button, the axes view limits will be 
  zoomed out, placing the original axes in the defined region.

* **Configuration of subplots**. Using this tool will configure the appearance of the subplot: 
  you can stretch or compress the left, right, top, or bottom side of the subplot, or the space 
  between the rows or space between the columns.

* **Save**. Save files with the following extensions: png, ps, eps, svg and pdf.
