E2.1 Resizing the plot

  On the toolbar is a control for changing the size of the plot. By default it
  is set to '100%'. Try changing it. The numeric values give fixed plot
  sizes; the 'fit to' options force the plot to scale with the window.


E2.2 Re-arranging the Display Window

  Each toolbar can be hidden, detached or moved. Try grabbing a toolbar's handle
  with the mouse cursor and moving it to another edge of the window.

  The Frames sidebar can be hidden - there is an icon in the toolbar, and
  an option in the View menu. This can give you back valuable screen space
  when working on a smaller display.

E2.3 Discover the Contouring icon - Part 1

  Create a new Contouring icon.
  Activate Contour Line Colour Rainbow and explore the available options.

E2.4 Discover the Contouring icon - Part 2

  Create a duplicate of your fixed_t icon. Do the 
  following modifications and see how they affect
  the visualisation:
  
  - Turn off contour highlighting and set the contour line 
    colour to black and the style to 'dash'.

  - Define contours by contour level intervals.   
    Set the interval to 5. Try an interval of 2.

  - Change the Contour Shade Method to Dot, and the dot size to 0.08.

  - Switch off Grib Scaling of Retrieved Fields - see what it does to the
    data values; the source data is in degrees Kelvin, but Metview/Magics
    normally performs an automatic adjustment to display in degrees Celcius.
    Notice the slight change in the format of the information presented in
    the Cursor Data when this option is changed.
    [Switch this setting on again before doing the next part]

  - Apply marker shading and ensure that
	- the values below -5 are blue
	- the values between -5 and 5 are green
	- the values above 5 are red 
    Zoom to the European area to see the individual markers

    Hint: use Contour Shade Colour Table

  - Modify the previous settings to have different markers 
    to the different intervals. For this you have
    to specify a marker list to Contour Shade Marker Table.
    
    Hint: first use 1/2/3 then try with other marker codes
