WeightHistogram( C )
WeightHistogram( C, h )

The function WeightHistogram plots a histogram of weights in code C. The maximum length of a column is h. Default value for h is 1/3 of the size of the screen. The number that appears at the top of the histogram is the maximum value of the list of weights.

    gap> H := HammingCode(2, GF(5));
    a linear [6,4,3]1 Hamming (2,5) code over GF(5)
    gap> WeightDistribution(H);
    [ 1, 0, 0, 80, 120, 264, 160 ]
    gap> WeightHistogram(H);
