The Weather Symbol Editor was introduced in Metview 5.14.0, with further development planned for the future. |

At ECMWF you need to use a development the latest Metview version to try out the editor. The command to run is:

The text item has two modes: a normal mode and an edit mode where the text can be interactively typed in or altered. In edit mode a frame is rendered around the text item to distinguish it from the normal mode.

Is redo-undo available?
Yes, there is a redo-undo functionality for all the symbol operations. You can access it via the toolbar buttons or using the Ctrl+Z (undo) Shift+Ctrl+Z (redo) shortcuts:

Please note that when performing zoom or dropping an icon into the plot the undo history is cleared.
Can I drag symbols out of the map area?
It is only possible for the markers, the text and the WMO symbols. The other symbols and shapes are all clipped to the map area, so any parts outside of it become invisible. The policy is even stricter for the fitted geo shapes: these are fully bound to the map area and none of their points or edges can be moved outside!
How does clipping work?
The clipping policy is based on the object type.
For markers, text and WMO symbols no clipping is applied. However, when we zoom the following things happen:
- items that were outside the map area stay at their scene (i.e. window) position
- items that were inside the map area before zoom but get out of the map will be hidden. They become visible again when we unzoom.
The snapshots below illustrates how it works.
For all the other types clipping is always applied (the example below shows how it works for a cold front).
