Hello, I use the following M'ca 7 expression to plot histograms in a linear bin range with linear bin heights, where the values are taken from the components of a vector lum. The expression I use to plot the histogram is: hh = Histogram[Range[binwidth*Length[lum]] - 1, Length[lum], lum &, Where: Range[binwidth*Length[lum]: gives the range of coordinates along the x-axis. Length[lum]: is the number of bins. lum: each of its components gives the height of each individual bin. I haven't been able to figure out how to integrate the "log" options to get both histogram heights (y-axis) and bin coordinates along x-axis in logarithmic units. Thank you in advace for any help.
