Layout    add an icon

Sophisticated layouts are possible in Metview, with multiple plots on a single page as shown below:

...

To demonstrate the plot layout facility in Metview, let's re-create the above plotting:

• create instantiate a new Display Window icon and edit it.
• click on the Add new frame button to create the first frame. By default, this contains just a single plot scene which uses a Geographic View. 
• select (left-click) this plot scene and click Expand selected frames to make it fill the whole area.
• divide it up into three areas as follows:
  • click Split selected frames, select 2x1 in order to obtain two vertically stacked frames and click OK.
  • select (left-click) the lower frame, click Split selected frames and select 1x2.
• give a different View to each scene:
  • drag a Cross Section View icon (either one you previously created or else a new one) into the top scene.
  • drag a Vertical Profile View icon into the bottom-left scene.
  • drag a Geographic View of your choice into the bottom-right scene.

...

Now do the following:

• Apply your the changes and Visualise this icon.
  
• drag the t_fc96.grib icon into all three of the scenes in the Display Window.
• apply some Visdefs:
  • drag shade icon into the cross section scene.
  • drag vdline into the vertical profile scene.

...

If you look at the Frames and, more interestingly, the Layers tabs, you will see that they are linked to only one of these scenes at a time. Try using the Active scene control to change which on is used. You can also right-click on a scene and choose “Select as active scene” from the context menu.

Experiment with this icon by changing other parameters, for instance, the font style and size. Also, multiple Text Plotting icons can be placed in this View:

• duplicate the note1 icon and rename it to note2.

• drag it into the Display Window.
