Description

From James Lord 

row_ws = CreateWorkspace(DataX="1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6",
                         DataY="1,1.5,-1.2,-1.6,1.4,  2,-2.1,2.1,2.3,-2.4, 3.1,3.2,-3.0,-3.4,-3.5",NSpec=3)

The resulting Color Fill Plot's right Y axis is from 1.0 to 3.2 with all the negative "pixels" filled with the minimum color (light blue). It ought to be -3.5 to +3.2.

James.
(Still using Mantid version 3.1.20140502.2025. My practical application is AsymmetryCalc to get muon polarisation and then ConjoinSpectra to make a map versus time and some log parameter such as magnetic field. Negative values are quite likely.)
