    Avoid floating point precision problems in chart scale
    Some charts were being drawn with a tick mark at positions
    close to but not exactly zero Eg: 2.187433298e-27
    This change avoids this problem.

    Histograms:  Ensure that the bins are aligned to an odd number of half bin 
    This has the benefit that the centres of the bins are aligned to integer 
    of bin widths, and thus the labels are shorter.  For example, instead of 
    -1.5 -0.5 0.5 1.5 2.5 we get -2 -1 0 1 2 which is more aesthetically
