Y axis label for asymmetry plot

[Anders Markvardsen]

1. Open MuonAnalysis interface

2. Browse and plot AutoTestData\MUSR00015189.nxs

This produces Asymmetry plot.

Change Y axis label for asymmetry plot to be 'Asymmetry'

Set this as critical since this is a common plot produced by muon users

[Arturs Bekasovs]

It seems that the YUnitLabel() is set correctly, but YUnit() is not:

ws.YUnit()
Out[11]: 'Counts'

ws.YUnitLabel()
Out[12]: 'Asymmetry'

MatrixWorkspace's methods use YUnitLabel(), which is why the units seem right in ADS view, but the plotting routines use the YUnit().

So we should set both correctly.

That's where it's done in AsymmetryCalc algorithm:

165: // Update Y axis label 
166: outputWS->setYUnitLabel("Asymmetry");

[Arturs Bekasovs]

After speaking to Martyn and looking at the code, it turns out it should be enough to set YUnit only - it is used as a label if label is not set, and those two would be equal for that case anyway.

Tester:

Check that the problem was fixed.

Check that Y units are now set correctly for all kinds of plots:

• Pair asymmetry
• Group asymmetry
• Group counts
• Group counts on logarithmic scale

Check that units are displayed correctly in both plots and ADS view.

Verify that system tests are passing, and when closing the ticket please merge the branch in system tests repository as well.

That seems to have broken system tests: ​http://builds.mantidproject.org/job/develop_systemtests_rhel6/128/

[Karl Palmen]

The plot from the Muon Analysis dialog box and those workspaces with Asym in name have Asymmetry as the Y axis name.
