Mantid Workbench Changes¶

New features¶

• Table workspaces can now have read-only columns added to them (ws.addReadOnlyColumn(<TYPE>, <NAME>)). Existing columns can also be set to be read-only (ws.setColumnReadOnly(<INDEX>, <TRUE/FALSE>)).
• The Error Reporter can now remember and prefill the user’s name and email.

Improvements¶

• The algorithm browser has been tidied to reduce the number of single algorithm categories.
• Cells containing vector data in a table workspace can now be viewed in the table workspace display.
• The browse dialog in the file finder widget now opens at the path specified in the widget’s edit box (if the edit box contains a full path).
• The font in python editor and IPython console are ensured to be monospace. It also ensures monospace on KDE Neon distributions too.
• There is now a warning in the settings to say that changes to Project Recovery settings are only applied after restarting Workbench.

Bugfixes¶

• Fixed an issue when save_as of a running script leads to crash upon script completion.
• Fixed arbitrary values not being accepted as the Start Time in StartLiveDataDialog.
• Fixed a bug where the option SignedInPlaneTwoTheta in ConvertSpectrumAxis would not give signed results.
• A number of plotting bugfixes have been made.
  • Fixed a bug where the toggle state of the Grids on/off toolbar button was incorrect when opening a 3D surface plot.
  • Fixed plot bins not working on data with numeric X-axis.
  • Fixed a bug where the z-axis editor dialog was being initialised from the y-axis for a 3D plot.
  • Fixed a bug with autoscaling of colorfill plots from within the figure options.
  • Calls to EvaluateFunction, when plotting a guess or fit result in the fit browser of a figure, correctly ignores invalid data when requested.
  • The axes limits of Waterfall plots will now scale correctly upon initial plotting and overplotting.
  • The Z-axis limits of 3D plots can now be set on linux machines.
  • The colour of the canvas is now preserved when generating a script from a plot.
• Fixed issue in DrILL when ASCII output was requested but the logs to save were not defined for that instrument.
• The About Mantid page now appears on a new full release, even if a recent nightly was previously launched.
• The instrument and facility combo-boxes are now always appropriately sized on the About Mantid page on macOS.
• Fixed a bug where copying data from a table displaying a matrix workspace was not working.
• Workbench will no longer hang if an algorithm was running when Workbench was closed.
• Fixed a bug in the editor where uncommenting using ctrl+/ wasn’t working correctly for lines of the form <optional whitespace>#code_here # inline comment.
• Commenting code in the editor using ctrl+/ will preserve indenting (i.e. # will be inserted at the position of the first non-whitespace character in the line).
• Empty group workspaces can now be deleted rather than needing to be ungrouped.
• Fixed a bug in Project Recovery when attempting to remove non-empty directories and raising the error reporter.
• Users are no longer able to add a peak to the Fit Property Browser by clicking with the interactive tool outside of the axes (which would cause an error).
• An unhandled exeception no longer occurs when attempting to open the Fit Property Browser on a bin plot.

InstrumentViewer¶

New features¶

• In the Pick Tab , a new panel allowing users to directly rebin their workspace now exists.

• The ability to rotate Ellipse and Rectangle shapes has been added.
• The integration slider now supports discrete steps when the axis has discrete values.
• A new button has been added to the Pick Tab to allow all of the detectors in the instrument to be summed in the miniplot without having to draw a shape.
