histogram with log scale

Hi, I am trying to plot an histogram, but i cannot set

    > 'yscale' to 'log'.

matplotlib transfers the vertices of the rectangles that make up the
bar, which by default have their bottom at 0.

Use the bottom kwarg, eg

  N,b,pb = hist(x, bottom=0.001)
  set(gca(), yscale='log')
