commit 8e98d2ec1b1620280d66820e323d82b00975374e
Author: John Darrington <address@hidden>

    FREQUENCIES: Fixed crash showing histograms of limited range.
    We had been using Freedman-Diaconis rule to select the bin width.
    According to the literature this is better than Sturges rule.
    However it cannot work when the interquartile range is zero, which
    will happen for datasets with small range.
    This change uses the Freedman-Diaconis rule and falls back to
    Sturges when the IQR is zero.
