UI & Usability Changes

Installation

Windows

  • IPython has been upgraded to version 3.2.1

User Interface

Instrument View

  • The instrument view will now save the state of the window to a Mantid project file.

Workspace Matrix View

  • Masked spectra (including masked monitors) will be highlighted with background colour (typically light grey).
  • Unmasked monitor spectra will have a dynamic background colour depending on the system settings (typically light yellow, as before).

Plotting Improvements

  • A new option has been added to the “Plot Spectrum” and “Plot Spectrum with Errors” dialogs. The “Tiled plot” checkbox enables such a plot to be produced as a simple right-click option.
    • When this option is used for a workspace group, each workspace will its own subplot, with all specified spectra in it.
    • When the option is used for a single workspace, each of the specified spectra will have its own subplot.
  • Using the Label Tool on a plot to add Sample Logs as labels now opens up a dialogue for the selected workspace with all the available Sample Logs listed and the ability to import the selected one onto the plot as a label.

Algorithms

  • Algorithms can now use a multiple selection list box for property input, MergeRuns and GroupWorkspaces use this so far. To select multiple rows use the Shift or Ctrl (Cmd) keys while clicking with the mouse.

Scripting Window

  • All matplotlib examples now work out of the box when run inside the MantidPlot scripting environment.

Progress Reporting

  • The progress reporting for algorithms has been improved, so that the progress is reported correctly when processing workspace groups or multi-period workspaces.

Documentation

  • Added Ragged Workspace as a concept page

Options Window

  • Within Preferences->Mantid->Options ticking a category off/on will now untick/tick all subcategories. Also having some subcategories on and off will now show a partially ticked box for that category.

SliceViewer Improvements

  • When opening the SliceViewer, it will default to showing the first two non-integrated dimensions
  • The SliceViewer now uses bin centres instead of bin edges when slicing on a histogram workspace
  • The SliceViewer will now save the state of the window to a Mantid project file.

VSI Improvements

  • ParaView updated to version 5.1.2
  • VSI will now save the state of the window to a Mantid project file.

SpectrumViewer Improvements

  • The SpectrumViewer will now save the state of the window to a Mantid project file.

Multi-dataset fitting interface improvements

  • Fitting a single dataset with a composite function no longer causes a crash
../../_images/MDFSetToLog.png
  • “Set to log” and “Set all to log” options have been added to the parameter editing dialog. These enable a parameter to be set to a value from a sample log for one or all spectra.

Bugs Resolved

  • Floating windows now always stay on top of the main window in OSX.
  • The sliceviewer will now rebin an existing binned workspace correctly.
  • 2D plots now display correctly for point data workspaces as well as for histogram data
  • Cuts aligned with an axis no longer generate an empty integrated line plot.
