Faciliate Multibank Fitting

[briantoby]

Allow grouping of histograms in sequential fitting: combined fits or for TOF instruments that produce multiple histograms.

Needs a tool (in controls) to select groups histograms into groups and save them (nested list?). Then in sequential fit, iterate over groups of histograms. Need to think how to display results in sequential fit table.

From discussion with @mguthriem: could group histograms by run number for ORNL. 1st step in this seems to be to creation of a structure that would link together related histograms (probably only of value for multi-bank TOF) and then have a command that builds the structure based on a string in the PWDR names.

Two other related things here, would be great to have:

• A composite plot with all histograms in a group. It would be crowded but would give a full view of a fit in a single plot.

• GUI that gives access in a single window to 1) profile terms (for calibration) and 2) HAP terms in user fits for all grouped histograms.

  Put everything in a single large grid? Perhaps a custom grid element that shows value, refinement flag, delta from start/default along with a custom element editor. Would want to make changes by column or perhaps by row.

Thanks for keeping track of these ideas. If I manage to get anywhere with my prototyping, I'll post updates here.

Have code to create groups. Can't do anything with the groups yet.

Now can plot grouped histograms:

From Malcolm: would be useful to specify a "zoom" range (in Q/d) that would be applied to all histograms to look at fitting of specific peaks.

• could be a menu item (with another to reset); copy zoom range? Push change on Zoom stack?

After discussion: grouping the x-axes would allow the existing zoom/pan controls to allow one to zoom in on a group of peaks (provided plot is in d/Q)

• implement as "x" key (shared x-axis implemented as 3985cbe)
• Need to document the new plotting mode

Things to do:

• setting/reseting grouped mode should cause a save & reload of .gpx file

• would like to do the same with Hist/Phase option

• "Show multiple" in instrument parameters -- can we have a control to set/clear all flags in row?
  (added to main in ed0deeb)

• with grouped histograms, create a Group entry in tree that has sub entries that display tables for selected parameters in a group

• Selecting any entry in the group should cause the grouped plot to be shown

Subentries to add under Group entry:

• instrument parameters (model on "show multiple", but selected by group)

• background

• limits

• HAP

• Sample params?

• N.B. each needs a command to copy to other groups in matrix fashion
