Mantid Workbench Changes#

Bugfixes#

  • (#40298) The Moments tab of the Inelastic Data Processor interface now moves the vertical sliders to the edge of the integration limits when new data is loaded for visualization.

  • (#40027) The Filter Events Interface no longer has a Split Sample Logs checkbox - since that option is deprecated and all logs will be split.

  • (#40473) colorfill plots with log colorscale will no longer cause errors when the below keys are pressed.

    • c, left, backspace, MouseButton.BACK - The behaviour is similar to pressing “Back” button on the plot’s toolbar.

    • v, right, MouseButton.FORWARD - The behaviour is similar to pressing “Forward” button on plot the toolbar.

    • r, h, home - The plot would be reset to Home view, i.e similar to pressing Home button of the plot

  • (#40577) Selecting multiple workspaces and right-clicking will now only display actions in the context menu that are compatible with every selected workspace.

  • (#40574) The FitPropertyBrowser should now be guarded against an occasional IndexError when interacting with plots.

  • (#40491) Calling fig.savefig() immediately after fig.show() will no longer cause a deadlock in the Qt event loop. This has been fixed by ensuring that all queued GUI events are safely processed before moving on to the next operation.

InstrumentViewer#

New features#

  • The modernised Instrument View has some new features. This new interface is still being developed but can be accessed, in its experimental form, by selecting (Experimental) Show Instrument after right-clicking on a workspace:

    • (#39949) Added the side-by-side projection. On instruments with no side-by-side panel positions defined in the IDF, this projection will try to optimise the arrangement of panels. For any detectors not in panels, they will appear in a grid, an abstract representation of the detectors.

    • (#40410) New option to either maintain (or not) the aspect ratio of a 2D projection of an instrument. This can result in a more efficient use of screen space, and clearer projections.

    • (#40508) One can now add and remove peaks. Peaks can either be added/removed individually, or all peaks on all selected detectors can be removed at once.

    • (#40578) Added an option to show monitors.

    • (#40623) Has a new Python interface to use the Instrument View in a Jupyter Notebook.

    • (#40101) Added a peak overlay. Peaks workspaces can be selected within the interface and those peaks will be plotted on both the projection and the 1D plot.

Bugfixes#

  • The new Instrument View also has some fixes:

    • (#40415) Peak overlays in the now work when an instrument has multiple detector IDs per spectrum.

    • (#40743) An error on closing no longer occurs due to a missing presenter.

    • (#40198) When deleting lots of peaks in a short space of time, a crash should no longer occur when erasing peaks.

SliceViewer#

New features#

  • (#40055) Sliceviewer now supports the Asinh colormap, similar to log but valid for zero values.

Bugfixes#

  • (#40477) Sliceviewer now corrects for dot-pattern artifacts when rendering sparse data in log scale.
