is_feature_available()to dynamically test for features available in the current Metview build - see Information Functions

METVIEW_LOCALHOSTis now set by default (set to 0 to disable)

-GNinjaoption to CMake)
Version 5.0.0 Beta
Externally released on 2017-12-20
Available internally ECMWF via the command "module swap metview/5b" on 2017-12-20 (Linux desktops, ecgate, lxc, lxop)
- At ECMWF:
Welcome to the beta release of Metview 5.0! This is very close to what we'd like to release in early 2017, so we'd appreciate testing and feedback. Note that this version requires Magics version 3.0.0.
New interactive layer management inside the plot window, allowing for faster plot revisions
Visual definitions can now be dropped directly onto specific layers in the plot window's sidebar, or even edited directly from within the sidebar! See Layer Management for more.
The colour picker in the icon editors now has support for alpha (opacity) values, and the interactive Display Window now also supports alpha values per colour. In Macro, these are specified as RGBA, e.g. "RGBA(1, 0, 0, 0.8)" for a red colour with 80% opacity (0 is invisible, 1 is full opacity). Note that PostScript output does not support transparency.
New colour gradients shading option
New options were added to the Contouring icon, facilitating more powerful colour scales within a single Contouring definition. Please see How to use the colour gradient editor for more information on this feature. More examples will be added to the Gallery!
FLEXPART support added
A new interface was developed for the FLEXPART Lagrangian particle dispersion model. The FLEXPART interface page gives an overview about the installation and setup of FLEXPART and also serves as a hub to access the icon documentation and the FLEXPART tutorial.
Macro Editor has new colour schemes
The Macro Editor has introduced two new colour schemes: solarized dark and solarized light. The colour scheme can be selected from the Settings -> Colour Scheme menu. The original colour scheme is called Metview and is kept as default.
Other features of Metview 5
- added MImport icon for adding image files to a plot (this only partially worked in the past)
- enabled line and symbol properties to be changed when in AREA mode in the Graph Plotting icon
- added new parameter Map Cities Text Blanking to the Coastlines icon
- added new parameters to draw a frame around the edge of the grid in the Coastlines icon, for selected projections that do not fill the page
- added the ability to plot horizontal bar charts via the new Graph Bar Orientation parameter in the Graph Plotting icon
- fixed issue where plotting a curve via the Table Visualiser did not work when the output was to file
- fixed issue where the Macro code generated by the Generate Macro function in the Display Window produced incorrect code for the Simple Formula icon
- the default output file format has been changed from PostScript to PDF
- the behaviour of Text Plotting icons (
mtext()in Macro) has changed slighly - see the Metview FAQ - old for details of this and how to compensate for it
- improved handling of netCDF data when the current variable is time-based - see NetCDF. Note that this is a change in behaviour, and existing macros may have to be revised.
- improved handling of netCDF data where a computation could lead to the overflow of the storage data type - see NetCDF. Note that this is a change in behaviour, and existing macros may have to be revised.
- improved handling of netCDF data where the current variable has scale_factor and add_offset attributes - these are now automatically applied - see NetCDF. Note that this is a change in behaviour, and existing macros may have to be revised.
- added a macro library function to draw a circle with a given radius in km onto a map - mvl_geocircle()
- fixed problem where the valid_date() function could give the wrong result given data with a very large step
- fixed problem where a Macro operation on a netCDF variable could overwrite the original file if it is a symbolic link
- change in behaviour: the
grib_get_xxx()functions now return
nilif the given key is not found
- change in behaviour: when indexing a vector like this: v[a,a], i.e. two indexes the same, the result will be a single-element vector; the previous behaviour was to return a number
- ensure that an incorrect indexing of a fieldset variable returns an error
- ensure that an incorrect indexing of a geopoints variable returns an error
- Vertical Profile: removed the redundant option Area 2 from Input Mode; please use Area instead, as it is identical
- the default value for the FLEXTRA Area parameter changed in the FLEXTRA Prepare - old icon. The new default is: -90/-179/90/180.
- fixed issue where FLEXTRA did not properly handle global GRIB 2 fields
- it is now possible to specify a relative path for FLEXTRA Input Path in the FLEXTRA Run icon
- a new FLEXTRA page was created in confluence providing an overview about the installation, setup and use of the FLEXTRA interface.
- the FLEXTRA tutorial has been moved to Confluence
- Macro Editor:
- revised which actions are available via the toolbar, providing a cleaner interface
- settings are now saved immediately (font size, show line numbers, theme)
- it is now possible, with care, to handle and plot very large GRIB fields (e.g. 1km global) - see Visualising large data files with Metview
- GRIB Examiner now correctly displays the sections of a GRIB 3 file
- new icon context menu action called "Delete" (shortcut is Shift+Delete). With this action the icon is deleted permanently (not moved to the wastebasket).
- new icon context menu action called "Copy filesystem path" to copy an icon's path to the clipboard
- selecting Log from the menu raises the existing log window if it is open
- added action in the Go menu to navigate to the Defaults folder
- Metview no longer asks for confirmation when closing down, unless there are multiple windows
- the Log window now uses a monospaced font for easier reading of aligned text
- improved the process of renaming icons from the user interface (when we edit the icon name the whole text is automatically selected; pressing enter in the text editor or clicking outside the icon confirms the renaming)
- fixed issue where the Desktop could get into a bad state if an opened folder is moved, or if Metview is started on a system that cannot see a folder that was open when Metview was last closed
Startup: fixed issue when starting Metview for the first time on a system where there is a pre-existing directory called
Qt: Metview now looks for Qt5 by default. To build with Qt4 (still supported for the time being, please build with
- Motif: completely removed the old Motif-based user interface from Metview's source code
